Laser Pointers on Amazon are Getting Out of Hand

[@TorqueTestChannel]

To be clear I think you SHOULD be able to buy the laser you want (we linked them above), and it's not illegal at all for them to sell it. If they list it as an industrial laser with class or watt rating it'd even help you find the best deal for the power! But they won't. Because enthusiast lasers is a small market, so they call them cat toy laser pointers, classroom aids and hiking flashlights which we're pointing at as being stupid. Cuz it is.

[@themagitechie9955]

FYI, any laser with more than 500mw or so can cause instant, permanent blindness even looking at a diffuse reflection. There's all those sketchy laser pointers, and then there's all those sketchy DIY laser cutters/engravers you'll see out there. Which don't include any form of laser safety enclosure or ventilation options or even tell you that you need one. You REALLY don't want to run a laser cutter with no fume extraction, especially not on acrylic or other materials that emit nasty fumes when burned. You do NOT forget the smell of burning acrylic. Ask me how I know 🤢. Maker's Muse already went into a lot more detail here, kzbin.info/www/bejne/Y2rLeouKbamAi7c If you're thinking at all about buying a laser cutter, I highly recommend you watch his video first. Even worse than all that are those quack "medical" lasers that StyroPyro covered in this video. kzbin.info/www/bejne/epPdk3x9oLWKY9E TL:DR, do your homework about laser safety, going blind instantly is no joke.

It might be worth to add another word of warning, and link this video: kzbin.info/www/bejne/b6WylIivltCeZrM Short summary, under cold conditions green lasers will have their wavelength shifted to the infrared. That makes them invisible, but not any less dangerous to eyes. If there's no infrared filter fitted, which I assume won't be on those incredible cheap units, it's actually freaking dangerous to eyes. As it's invisible, there's no lid closing reflex and the uneducated isn't aware of what's happening.

The scary thing about many cheap green lasers, is that they use an infrared diode and a frequency doubler crystal to create the green output. If they get cold, the doubler can stop working and it may appear that there's no output, but it's still blasting high power infrared. They also leak a lot of infrared when working correctly.

[@stevenrs11]

And even when warm, they can put out many times the power of infrared than visible green. I don't trust green lasers without testing (using a phone camera that can pick up infrared, and a prism/diffraction grating).

[@Teth47]

Another very important point about the cheap green laser pointers (and other cheap green laser products in general) is that they are almost always DPSS lasers, which means they are actually an infrared laser rated at about 5x the output power of the green laser it's a part of behind a nonlinear crystal. The most expensive component of a DPSS laser is usually the IR filter after the nonlinear crystal that prevents the 4/5 of the IR beam that isn't used by the crystal from leaving the laser. It is also technically optional since the laser works without it. What that means is that cheap green laser pointers are also infrared lasers, and very powerful infrared lasers at that. Infrared bounces off of different things than green light, so the two beams can also end up misaligned with one another, meaning that you can have a visible beam that might even be at a safe intensity, but also an invisible blinding laser beam just bouncing off in some other random direction. If you don't understand what a DPSS laser is and how it works, do not buy cheap green laser pointers, the savings aren't worth your eyes.

[@dutchdykefinger]

can i use them to play CDs though? or burn CDs, perhaps literally? :) seriuosly though, this "Infrared bounces off of different things than green light, so the two beams can also end up misaligned with one another, meaning that you can have a visible beam that might even be at a safe intensity, but also an invisible blinding laser beam just bouncing off in some other " that's the craziest concern alright besides the reflective properties of certain colours and materials and how they may still bounce ir to different degrees without you really being able to see any of that behaviour IR is a lower frequency too and therefor will travel a greater distance for the same energy, and therefor inherently has more potential to make more bounces too, assuming the amplitude is the same (amplitude as a function of, distance * lens angle:wavelength ratio) easy proof: the old squiggle in the rope, get 2 ropes of a meter, then deform one to make 4 sine waves exactly 10 centimeters from the bottom to the top now do the same with the other but with 6 waves instead... a lot of horizontal length is now lost to packing density vertically, this is why lower frequencies travel farther for the same beam width and because of that frequency index of refraction comes into play too when used on water or glass or even thicker diffuse solid i mean, diffusion like using a sheet of paper to light up a room with a small flashligh, really is just photons scattering in random erratic directions through the material and spreading the light across a wider surface as a result of those bounces, i guess you can throw it at a prism and perhaps see a bit of the visible red still get seperated before it goes into ir, also, using the cam on your phone, it usually does have IR filters, but still sees more red than most human eyes do, you can strip the IR filters from webcams quite easily too and use them as ghetto heatcams

[@dabeaniebeaner]

[@alexwang007]

Many of the green lasers are poorly filtered DPSS lasers as well, so they are far more dangerous that they could appear.

[@the_undead]

@@atomanni-k5m yes it is just from the reflection, the reason why lasers are so dangerous even though their output power may seem pathetic compared to most other things is because the power density is off the charts, it is not that hard to make lasers with a power density greater than that inside of a nuclear reactor (at least compared to what you would think it would take to get something with that kind of power density) a 500 MW laser does not come anywhere near that kind of power but you don't need anywhere near that kind of power to cause significant problems. And then when you consider the fact that your retina is easily the most fragile part of your entire body (I don't know what the melting point is exactly but I know it's not very high) causing permanent blindness with lasers is actually quite easy once you start getting above like 50 ml power or so

A few years an HVAC contractor came in with a laser IR thermometer, and she saw the dot and started reacting the same way, only worse. I did some research and found that this is not uncommon.

In graduate school, I did quantum electronics -- lots of lasers. Even the very low power lasers (the ones 5W and less) can cause noticeable eye damage over time with sufficient exposure. I, personally, would not recommend using them as toys for kids and pets. And, if you're around laser scanners (grocery stores, garage gates), I recommend you consciously avoid looking at the laser. When I'm at clubs that use laser lighting, I either find a way to avoid looking at the lasers or I leave. If you work at a place that uses lasers (say, if you're a grocery store checker, warehouse scanner or a club DJ), you'll want to be extra careful because you'll be around the lasers all day, and it is the continuous long-term exposure that can be dangerous with low-power lasers. When I was in school (1980s), lasers as strong as the lasers used by many clubs today would have required a health physics audit and warning signs -- I'm not sure why the regulations changed (or maybe they didn't, and everyone just ignores the regulations).

[@MarianKeller]

Lasers used in old barcode scanners, modern designs just use red LED lighting and an image sensor, are class 1 and therefore eye safe, there can't be any cumulative damage. Same for show lasers, while they might easily fall into class 4 and are extremely dangerous on their own, laser show operators must ensure that exposure of the general public stays within safe limits. Now sadly you shouldn't really trust laser show operators, since some of them might simply operate illegally or are stupid. For a new year party, my town set up a laser show on the main town square.

Is spamming keywords in the title of your product lying, in a legal sense? I don't think so. Technically, you can use these for the dog, cat, classroom, teaching, hunting, etc. Yes, you'll possibly blind everyone involved, but these lasers still function for all those purposes while you and your subjects retain some amount of vision. There's a reason why "caveat emptor" is apart of legal doctrine. Buyer Beware, it's up to the buyer to determine the quality of the product by doing their own research. Such as watching videos like this which independently test product claims!

Those Things are no joke. They are basicly cheaper and simpler versions of Lasers used for stage and lighting applications. Most of the time they are class 3 a/b Lasers so they pack quiet a punch. I got permanent eye damage from playing around with them when I got my first Stage Laser.

[@DracoOmnia]

On the fobserd mine came with an orifice that increased how diffuse the laser is (aka the size of the dot at range), this dramatically decreases the optical density (energy per dot area) which can make it closer to "eye safe" (a relative term based on 10 seconds continuous exposure not causing permanent damage). Fully diffused I use the laser with my dog on our 5 acres. At the ranges I'm looking at and eye exposures of fractions of a second at worse he should be fine. I was qualified as a laser safety officer in the navy, so in my case I have some informed consent here, I understand the device, the risk and made a choice. Unfortunately most people buying these lasers are clueless and can and will unintentionally blind themselves, friends family, airline pilots, sports ball players and their pets... Seriously, do some due diligence when buying these because the government isn't enforcing its own laws these days, expect zero consumer protection

[@quarkonium3795]

One kind of scary but also kind of cool thing is that lasers can get a LOT more powerful than the ones shown. I work with a 130-watt laser and the terrifying thing about that one (apart from, y'know, 130 watts) is that it's infrared so if you're unfortunate enough to get your eye in one of the beam paths you won't even get to see it before you hear the fluid behind your eyeballs boil away and you go permanently blind. The one I work with is over $150K because it's from a reputable company and it has to have incredibly optimized specs and not just a boatload of power, but I believe Styropyro did a video where he found a medical laser of similar power for under $1K on eBay because it was broken but only needed some minor repairs so this stuff is out there if you know what to look for.

[@brunoviaris467]

Your measures are very useful for the safety of users. As for judging the quality of the laser, you might want to also measure the power of the green lasers behind an IR blocking filter: often cheap green lasers use a low quality filter, or none at all, and they emit a large amount of 808 and 1064 nm, which are usesless regarding range, and dangerous. So a well filtered 10mW laser (10mW 532nm + 0 IR) would be much more visible than a loosely filtered one with a total power of 50mW = 2mW 532 + 48mW IR

[@zachnilsson4682]

If you want to get a quicker/maybe more accurate laser power meter, I used one from ThorLabs when I was in grad school. It used a silicon diode so it was good from 200-1100 nm and was instant read. I can also confirm that ThorLabs will ship to a residential address.

[@asdf35750]

It's worth noting that, while they may be legal, 5mW lasers are NOT intrinsically eye safe. Any visible wavelength laser with an output power greater than 0.39mW (that's about ONE THIRD of a milliwatt) can cause eye damage. A 5mW visible wavelength laser is class 3A. If you get a direct flash to your eye from a class 3A laser, it can cause permanent eye damage in less time than it takes to blink. A class 2 laser (less than 1mW) is usually considered safe because the exposure is limited by your natural blink reflex.

[@lagoat4]

The use of laser rated goggles for the higher output units cannot be overstated. Eye damage or blindness can occur in an instant even from a reflection, and is permanent, as in irreversible. So beware, and please do not give them to your children.

Would be nice to have power wavelength measurements as some of these different colour lasers have a lot of IR power from poor frequency conversion and filtering. It’s quite a surprise to find a dull looking pointer with 3mW of visible and 20mW of invisible. It’s funny when the lower number is better, good job raising the issue though.

[@ericwilner1403]

Bezackly. Specifically, the green lasers are almost always frequency-doubled diode-pumped Nd:YAG lasers (DPSS: diode-pumped solid state, plus the doubler), so there are two strong IR wavelengths present in addition to the visible green. Cheap lasers don't generally include a filter to block the IR emissions, so the apparent brightness of the beam isn't a good indication of the total power. I went looking for a cat toy built around a direct-green laser (no IR involved); failing to find one, I ordered a batch of direct-green modules, which should be turning up in a week or so. If those seem safe, I'll build a pointer around one for safe cat-teasage. (Have to dig out the ol' power meter from storage.)

A lot of the energy is completely invisible to the naked eye and with powerful lasers, even looking at the laser point on a surface might be enough to cause eye damage. Additionally, you need to ensure that any safety glasses you use filter out the right wavelengths for your laser, or they won’t help at all (they have to let through some of the light so you can see) >0.5W lasers are INCREDIBLY dangerous, they should not be used without safety glasses under any circumstances, and the fact that they’re speced over 100fold low is scary as hell

If you can see the beam indoors with lights on, then it's probably above 5mw. Seeing the beam means that you can move it back and forth and still see it, rather than being able to faintly see a stationary beam while you're looking directly down it. You'll be able to just make out a 5mw beam with lights on, and you'll certainly see the beam without lights. It won't be bright, but it will be visible.
