Why don't you mention the issue of inertia in any of these weapon videos? Space may not be a "perfect" void, but it's near as you can get. The range of a missile on earth would be dramatically increased in space and, my understanding, would be theoretically infinite or nigh unto. After all, if nothing is in the path of your projectile, it has no reason to slow down or stop. Am I airing a number of misconceptions here? I thought one of the major problems with lasers has been their short range per energy expended as compared to missiles, which might not be as dramatic in space, but still a factor one would assume.

The expanse got it wrong. It didn't have lasers because it just didn't want to. Not because it is not a viable weapon . Seriously if people like you keep thinking the expanse is gospel you will just lose credibility. There is a point where you just say no this is wrong. The expanse is wrong.

In Nebulous:Fleet Command (one of the footage sources of the vid), in-game descriptions place emphasis on that the big, anti-ship things aren't lasers, they're beam weapons that siphon off material from ship's reactor cores. They emit a very fast plasma beam that ablates material. In-Game, they're the shortest range, highest engergy intensity and deadliest weapons, shewing through most ships in literal seconds but needing dedicated strategies and ship builds to work.

And yet they are useless as weapons even now. The development of another technology in 2018 that wasn’t expected to be developed until decades from now, arrived unexpectedly, and suddenly the billions we (and others) had spent on High-Energy Laser Weapons suddenly became a sunk-loss. That development is also making spacecraft lighter, and able to devote far less mass to re-entry shielding than previously, allowing more “other stuff” to be carried. But the real killer is something that is now still in the labs: Hyper-reflective/refractive Metamaterials. Their Refractive/Reflective Properties do not arise from traditional optics, or highly polished surfaces, but from the arrangement of the Molecules that compose them. Thus things like scratches, dirt, etc. don’t effect those properties, which are indices of Reflection/Refraction near ∞. The newer Ultra-Black Pigments are made using the same sort of technology, but rather than, like the Hyper-reflective/refractive Metamaterials that have an arrangement of Atoms/Molecules that prevent the light from contacting the material (and thus “Bending” it someplace else), the Ultra-Black Pigments have an arrangement of Molecules/Atoms that absorbs everything thrown at it (There are some very profound applications for that if they could be combined with Superconductors to producing power on an enormous scale from a very small amount of light in any wavelength). Some of these are currently being used in new Solar Power Applications, high-powered Optics and Telescopes to eliminate Light-Pollution, and so on. But the limit of Refraction/Reflection → ∞ on these means that we couldn’t build any kind of laser that was short of consuming the entire power output of a star to leave enough residual photons un-reflected/un-refracted to transmit their energy (heat) to the material to overcome it. There is a LOT of resistance to accepting this (much like Drake’s Hammer’s Slammers creates resistance to the impossibility of Tanks being Hovercraft - I got to meet the leader of the US Army Team who evaluated the PACV, and then helped develop the LCAC. He summed up the stupidity of making a “Tank” out of a Hovercraft as “WHY would you want to make a tank out of an Air-Hockey Puck that crashed every time it fired its weapon, or got hit by one? Never mind that they are not nearly as fast or “All Terrain” as they have been made-out to be.”) given the prevalence of Lasers in Science Fiction dating back to their invention in the 1950s. And the ubiquitous “Ray-Gun” of Science-Fiction causes a false association between Laser Weapons and High-Energy Particle Weapons, which are at least throwing Mass at an object, even if not a significant amount (This was another area a Physics Professor I know at UCLA has a bone-to-pick with, as he points-out that the purpose of a Particle Weapon would be more to create secondary effects for other weapons to exploit. Or to kill the biological component of a Target without harming the physical structure of it). Lasers turn-out to have an incredibly narrow window of utility as “Weapons,” and even narrower if the civilization developing them has an active Space Program (Heat Shields for Spacecraft are basically armor for protection from Laser Weapons). And here on Earth, that window slammed shut in 2018 when the Scalable Manufacture of Hardened Aerogels became a reality. While the USA’s laser (and England’s, France’s, Germany’s, Russia’s, China’s, etc.) still remain viable for use against insurgents, terrorists, pirates, and so on… The major Countries and Nations with the wealth to do so can easily add the thin film of Hardened Aerogel required to make a Laser a poor weapon to use against such targets. They have been very quiet about the whole thing, given the poor PR surrounding it.

Laser weapons are the primary space combat weapon in the Kris Longknife book series. Earlier in the series most warships use a layer of ice as ablative armor against laser attacks. Ships engage while rotating at 10-20 RPM to prevent burn-through down to the hull, causing most hits to carve long spirals into the ice instead of substantial damage. There are even some instances of ships intentionally melting their own ice armor as emergency cooling to give their lasers a higher rate of fire.

He understood how the main benefit of the weapons were heat exchange, and one thing that the Chiss would do would be to launch “Breacher” missiles at a target, loaded with strong acid that would have an effect of darkening and pitting the armour of an enemy warship so that the Lasers would be more readily absorbed by the target. elsewise, the Chiss would adjust the frequency of their lasers so that they would be better absorbed by the target depending. really more felt like a more thought out take on Star Wars weapons than seen elsewhere

This would render any LIDAR unable to detect whatever has been coated with these materials (and drastically reduce the effectiveness of any LAZER weapons used against it as well) thus likely forcing a return to much less accurate (and more easily foiled) RADAR for targeting. And with them being both highly durable (they work on the nanoscopic level so scratches will not effect them) and easily applied to anything that can be painted, and suddenly combat ranges drop immensely (and overall accuracy).

This is why I love the weapons systems in the Honorverse. Guided missiles for long range combat (although they're actually bomb-pumped lasers with a 'rocket' on the back), and laser weapons for short range combat. There's no place for kinetic weapons because they're simply too slow for any practical use beyond planetary bombardment. And when the laser weapons fire, they hit before people realise they've been shot at. A lot of the combat strategy in the books are about opposing fleets trying to stay out of each others' energy weapon ranges unless they're enjoying an overwhelming supremacy in numbers because being in range basically means you can't dodge or defend against the energy weapons; you just have to tank it.

@@DarthBiomech Honorverse ships use gamma-ray and x-ray lasers with big optical apertures so difraction is not a problem at the ranges they fight. The formula to know the spot size of a difraction-limited laser at a given range is: 1.22 * wavelenght in meters * range to the target in meters / diameter of the aperture in meters Honorverse ships typically fight at ranges of 500,000 to 1,000,000 kilometers. So for example if they carry laser weapons with 1 meter apertures and use a wavelenght of 10 picometers that means those weapons can concentrate their energy in a spot size of 6.1 to 12.2 milimiters, so difraction should be not a problem at all. And at this distance light lag isnt much of a problem either as lasers travel at 299,792.5 km/s meaning the enemy will only have 1.668 to 3.336 seconds to move out of the way (and lasers are invisible in space and the ships can attack using multiple weapons simultaneously but aimed at different points in space) so they will be not easy to dodge. And as AngryDuck! said lasers were prefered as close range weapons anyway. For long ranges they mostly used relativistic missiles with energy shields carring nuclear-pumped warheads.

One of the things that U.S Navy learned from actual lasers, namely the ODIN laser on Burke classes and LWSD on USS Portland, is that since laser required some precise aiming mechanism, you essentially designed a long range electro-optic precision tracking/targeting device. Which is a surprisingly good substitute for radar since that is passive tracking from target EM emissions, while radar is active tracking by detect the reflecting radar waves. This way a warship could track the precise location of its target, without giving away its own location or even present.

One of the benefits of pulse lasers over continuous beam is that the plasma cloud released by explosive vaporization absorbs some of the laser energy, robbing it of it's efficiency as a weapon. Pulse lasers can strobe in such a way to let the plasma dissipate before pulsing again, making sure more energy makes it to the target and isn't wasted in the fireball.

Idea for overcoming angled armor - nesting lense. Primary lense is larger in diameter than the secondary. Primary beam pre heats your target material and the beam bends to whatever angle said material is at. The secondary lense is where the damage happens - similar in frequency to the primary beam it won't bend or distort as much. With target material pre heated the punch is far greater and will cut through faster. It will be a larger system and require more cooling and energy but to say "angled armor! Aren't you cute!" As you carve your target up like a thanksgiving turkey. Waste heat can be an issue if your using straight heat sinks or radiators. Pump something like a molten salt or low melting point metal like bismuth through your heat sinks or radiators and you can then recycle that heat into capacitors or battery system for a quick recharge. If you really want some fun- constant beam lasers. Lasts as long as your cooling system can handle the heat and reactors can put out power. Instead of short burst or a couple of seconds flash, it's constantly melting and cutting through armor. Think Spartan laser from halo 3 or for us battle tech people MechWarrior 3 pirate's moon expansion - a few seconds of directed laser power on a location.

Speasking of games that do lasers realistically, along with space-ship design: Terra Invicta. The game actually uses the gaussian equations to calculate the diameter of the laser versus the size of the mirror and range to calculate damage output. Similar to what the video describes, they even factor in optics size - as every laser has basically the same energy output, to calculate the relative effectiveness versus range. Plus, it adds cool concepts like Delta-V for maneuvering and as they talked about above, also radiators and heat-sinks.

keep in mind that lasers consume a colossal ammount of ammo in the form of electricity, "laser ammo" becomes the weight of your reactor and it's fuel and also, think of it that way: you need to cut in two a piece of wood, what do you use, your axe or your flashlight? the point here being that light is absolute trash at inflicting physical damage due to it's non physical nature (personally I'm in the camp that photons do have a mass and think the camp who think they are completely massless is wrong, but whatever the case, they have an extremely small ammount of mass no matter what and will always be light hitters as a result) the ways to increase laser damage have always been to pack in more energy (smaller wavelength) or increase the ammount (higher laser luminosity) they always go at the speed of light, and despite going that fast they do almost no kinetic damage, we don't know of any way to increase their kinetic damage, as such the only way to do "damage" light has (that we know off) is by transfering heat, which is an absolutely terrible and inefficient way to destroy something, compared with shoving metal objects going very fast through it

An issue with mirrors is that they get dirty. Dirty mirrors collect more heat than they reflect. Even if you clean the mirror, it is now damaged and will continue to burn. I've built and run die cutters and a temporary solution was to spin the mirror so the bad spot was in another position. There's some good opportunity for a weapons failure in the middle of a fight scene or testing experimental armor in battle. I kinda wish I could find another laser related job. It was fun and interesting playing with lasers. I also basically had a free engraver to play with.

As someone who actually worked with weaponized lasers most people do not seem to understand how they work. An aiming or adjustment beam is fired first for adjustments to the primary beam. Which people forget even very high energy beams will refract. They very much so have limits to their range. The major limits on these things are power supply and cooling, for the record in vacuum cooling is actually harder than in atmosphere as there is no material to exchange heat with.

Short version - there is no stealth in space. A ship at the freezing point of water (~270 Kelvin) will stand out like a flare against space's background 3 Kelvin. A decent commander will be aware of local heat sources and have satellites/probes/allies watching the space between them and the heat source so nobody can hide in it. If you try to maneuver, then you are either turning on a powerful engine that can be easily seen, or are using cold-gas thrusters that have very low acceleration and delta-V so will take weeks or months to be in position. In the meantime your opponent uses their nuclear engine to move a small distance and throws all your calculations and maneuvers into the trash.

You definitely want to retract radiators before getting into combat. Otherwise radiators are large and fragile items critical for ship operation, and not retracting them means an opponent can cripple you easily. The game "Attack Vector: Tactical" has this as a universal 'I Surrender' signal. If you extend your radiators it means your ship is about to cook from its own heat. If you keep firing while your radiators are extended, an opponent will have an easy time shooting them off and then you are in real trouble.

@@paulshealy1863 Mass Effect actually reconciled both your points when talking about it's science behind the heat management systems of starships. An excerpt from the codex: *Dispersal of heat generated by onboard systems is a critical issue for a ship. If it cannot deal with heat, the crew may be cooked within the hull. Radiation is the only way to shed heat in a vacuum. Civilian vessels utilize large, fragile radiator panels that are impossible to armor. Warships use Diffuse Radiator Arrays (DRA), ceramic strips along the exterior of the armored hull. These make the ship appear striped to thermographic sensors. Since the arrangement of the strips depends on the internal configuration of the ship, the patterns for each vessel are unique and striking. On older ships, the DRA strips could become red- or white-hot. Dubbed "tiger stripes" or "war paint" by humans, the glowing DRA had a psychological impact on pirates and irregular forces. Strip radiators are not as efficient as panels, but if damaged by enemy fire, the ship only loses a small portion of its total radiation capacity. In most cases, a vessel's DRA alone allows it to cruise with no difficulties. Operations deep within solar systems can cause problems. A ship engaged in combat can produce titanic amounts of heat from maneuvering burns and weapons fire. When fighting in a high heat environment, warships employ high-efficiency "droplet" heat sinks. In a droplet system, tanks of liquid sodium or lithium absorb heat within the ship. The liquid is vented from spray nozzles near the bow as a thin sheet of millions of micrometer-scale droplets. The droplets are caught at the stern and recycled into the system. A droplet system can sink 10-100 times as much heat as DRA strips. Droplet sheets resemble a surface ship's wake through water. The wake peels out in sharp turns, spreading a fan of droplets as the ship changes vectors and leaves the coolant behind.*

Reflective paint like white paint has been shown to negate a MASSIVE portion of heat thrown at an object, its quite literally what we use to shield our spacecraft from the sun. Its limit is the thickness of the paint vs how hot the heat source is, if your reflecting 99% of all heat energy from a laser, but that 1% is still enough to fry your space craft, layering your paint is critical for survival from lasers. Most importantly however, is the second issue with white paint or any contact defense, in space there is only one way to radiate heat, and that's by radiation not by absorption from outside sources like air, though space does have free-floating gasses, it's not enough to leak heat into at sufficient amounts, if at all. so radiators and materials that can't hold heat very well or systems that knock off entering hot electrons will make sure that you don't store heat from a beam of light. You can even run cold fuel through your shielding to spread out that heat, and pre-heat your fuel for faster burn and preform evasive manuevers with it from other weapon systems a enemy craft may have.

Although not a downside per say, another limitation of lasers that should be noted is that collimation is not infinite, as the beam gradually and inevitably broadens with distance, which disperses the precious photons. So, yeah, even lasers have an effective range, which may or may not be drastically decreased by angled mirrors coated with the right materials to deflect their wavelengths (even in infrared you can reflect light, it just so happens it's not the same material for reflecting visible light).

Honestly I wanted to avoid lasers in my setting? But you have changed my mind. I think I will still have the rule that they're a bit too hot and unwieldy to be a ship based weapon, but I think have them as large scale weapons. Used more like a strategic weapon than anything. So thank you for changing my setting!

Lasers aren't long range. Not by the scale of any plausible space combat. This is one thing the lore of the original Mass Effect games understood well, but few others do. Diffraction is much bigger issue than the video makes out. A laser of, say a 1cm beam diameter (very wide for just about any laser) at roughly visible wavelengths will have a diameter of 5cm after only 300m, will have doubled to 10cm after 2.5km, doubled again to 20cm after 11km, will be 50cm wide after 60km, and a full 1m wide after ~270km. At that point the intensity (and so damage) done by the laser has decreased 10000 fold (that's ten thousand times weaker - not a typo). Go much further than that and it's just a torchlight. Using higher frequencies only helps a little, because of the underlying exponential growth (e^[sqrt(x)] to be precise). Unless you can make some isoteric gamma ray laser or something, but that's so different as to hardly be a laser, certainly not one to compare with the usual scifi stuff. These are short ranges by modern missile technology on earth, where line of sight is limited, the curvature of the earth gets in the way, and the atmosphere slows everything down. In space there's every reason to expect fighting to be at much, much, longer ranges. Sure, a laser gets there a few seconds faster than a high velocity rail gun slug, but what's the point if it's too diffuse to do anything by the time it gets there? Better to fire slugs in a wideish spread at slightly different velocities so they form a scatter that reaches the target simultaneously in a wide enough pattern that they can't all be dodged. Or missiles that can home in. As ME recognised, lasers make the most sense at short range point defence, where their speed is vital in intercepting missiles and the like, and before diffraction ruins your day.

You missed a couple anti-laser techniques. 1. Obscurment, smoke, dust, or nanoparticles 2. Spin. Used effectively in Mech Warrior. If the laser is not instant, but delivers energy over time, spinning will distribute that energy over larger area.

"down near the sun for all the free energy" If you're going to do that, just go with Archimedes' mirror writ large. Like SAPL from the *Troy Rising* series. While most of the characters refer to it as a laser, it's pointed out multiple times that it's not really a laser, it is collected and focused solar output.

Food for thought on mirrors, cooked by astronomy, a fine mix of astrophotography, visual observing and cosmology: An inexpensive, but not cheap (i.e. not plastic toy crap) telescope mirror, as in 'can be obtained in optical tube assemblies (i.e. a telescope) for half of what someone working at mcdonalds can make in a week have reflectivity around 95%. That is just cheap stuff and a ton of that price is because they are ground to precise & smooth shapes necessitated for optical telescopes by their very nature. Even these entry level telescopes are so good at being the mirrors they need to be in shape, smoothness and reflectivity that they are literally limited by diffraction itself when looking at any image defects one might see. They are simply that good at reflecting things as well as where they specifically direct that reflection (such as to a secondary mirror which then sends it off to an eyepiece in a Newtonian style reflector... I got one of these, with a mechanical clock drive mount (GEM) for $500ish some years back 150mm f/5). Of course I am talking about mirrors made of glass specifically designed for its thermal properties as well. Telescope mirrors have to be as close to the ambient temp as possible to minimize distorting the air it is in close proximity to (just this little bit can show up in an eyepieces image, again highlighting just how good the reflecting is) but ideally need to be able to keep above freezing, since they are radiating their heat out into the space they are looking at, it is easy to frost over a mirror in colder months (like the time you get looking _out_ from the galaxy in the northern hemisphere, winter.) Different solutions exist like heaters that wrap around the mirror as well as the thermal properties of the mirrors material itself. I personally prefer the floor heaters of my truck as my only other active method would involve fire. But think of the implication on the material in a space setting. Unless near a star, or getting blasted by thrusters or something, you could design something that are to mirrors what ice is to water. Something that takes time to get to where you want it, just so that you can take 1/100 the time changing it back to what it was before. Out in space, you see how little the sun gets to the outer planets, now just imagine those mirrored surfaces radiating whatever heat they have into the void in an attempt to equalize its temp with whatever the hell it is radiating too, like dust that is a few degrees above absolute zero. A vain attempt in the end, but one a mirror will attempt with all it can muster. Just some thoughts on mirrors and reflectivity in a space setting, based on my visual observing and astrophotography since the 00s. addendum: I just took a quick look and the same OTA that was used for that scope+mount I mentioned from a decade or so ago, is still being used for the modern version of the same combo. But the rest of it has been upgraded (different eyepiece, different GEM, different finderscope even, but the same old telescope tube. And not all that much more in price as well, but that is to be expected since things like inflation and the upgrades to some of the kit used are things. addendum 2: Back when Herschel (1738-1822) was making his own mirrors and discovering things like Uranus, using speculum (1/3 tin, 2/3 copper) as the reflective coating, they were getting at max around 2/3 reflectivity... with a metal that tarnishes like silver on meth. By the 1850's people had already bumped that up to 90% with the use of, well, silver. Which was not only better in that regard, it is easy to remove from the glass, rendering the glass back into a blank that can then be rehabilitated into a perfectly good mirror with little effort compared to making it in the first place.

Also important to know is that the shorter the wavelength of your laser is the smaller a mirror you need to focus on targets at the same distances. This allows a far higher effective range than a long wavelength laser of the same size has.

One of my favorite Military SF series is the Kris Longknife series. At the start of the series the larger warships use ice armor as a laser defense.
