The Extreme World of Ultra Intense Lasers - with Kate Lancaster

[@MrTeknotronic]

Well I, for one, appreciate people who make lectures like this.

[@GothAlice]

The passion evident as she speaks is moving, and contagious. Now *I'm* excited about fusion projects like the National Ignition Facility (who are attempting the inertial confinement fusion w/ gold hohlraum approach described).

[@godfreecharlie]

Yeah, the balloon demonstration was astounding, stunning. All in all not a lot here.

Kate teaches mathematics to first year physics students at York uni. We love her! She’s so funny and lovely.

[@carreg-hollt]

The whole lecture had me smiling and laughing (and almost understanding some of what she described) but Oh God! what a difficult and po-faced audience. Kate's enthusiasm nearly had me convinced we will have cheap clean energy in my lifetime. Except nobody will ever trade a million dollars for 20¢ It's interesting to see that the ELI-NP project managed 10 petawatts early in 2019, a hundredfold increase on the NIF in 2015. There's some work to do to get 10^25 watts by 2025...

My feeling that any problem can be fixed with more lasers and more magnets has been reinforced by this video, thank you.

[@PauloConstantino167]

LOL

[@miallo]

In my lab we are studying magnets with relatively high powered lasers (so the thing almost at the bottom of the diagram at 15:30 wich says HHG. Don't get me wrong: our pulses have the same energy as the combined German energy production, but notice that the scale is logarithmic). So we are basically studying duct tape with WD-40???

[@cryora]

If you'd rather use chaotic incoherent broadband light for your light-matter interaction experiments, go right ahead. I'm using a laser. If you'd rather use a screwdriver as a chisel with a hammer to machine your parts, go right ahead. If you'd rather use a butter knife for woodworking projects, go right ahead.

[@ruthmoreton6975]

Mesmerising lecture. To the critics - you get up there and give a one hour non stop lecture on your favourite subject from mostly memory. I dare you. Kate did that, while on camera for the BBC knowing it was going out not just to the audience but likely a million or so viewers too.

[@cinnion]

Add to that the fact that if she is anything like the typical person in the science/engineering fields, she may in fact be fairly introverted and finds the idea of speaking publicly spooky at a minimum. Many of us are not anything like what you see with Carl Sagan, Neil deGrasse Tyson, Bill Nye, and some others (or what BBT might have you think). It is one thing to stand in front of students, another to stand in front of your peer community, and then something far, far different to do it in front of the general public, being recorded and having who knows how many more view the talk several years later. Take your worst interview, multiply it numerous times and compress it down into a single interview, and that begins to describe the experience. She did wonderful in her presentation.

[@digitalranger4259]

So.... was this lecture a last minute thing? I have no doubt that this scientist knows her stuff, and I was really looking to watch this and gain some knowledge of one of my favorite subjects. But her delivery is so uncomfortable, it comes across like she's doing someone else's lecture, and takes away from the material. I'd love to see an edited, non-live version of this, allowing her to retake any stumbling dialog. She is obviously so passionate and excited about her work, I just want to see it presented in it's best light. (No pun intended.)

[@prof.m.ottozeeejcdecs9998]

[@elliottmcollins]

Good lord, the critical tone in these comments is so silly! This was really interesting and fun to watch. There are as many critics saying it was too simple as there were saying it was too complex, which suggests to me that 1) it was just right and 2) people love to criticize strangers on the internet.

[@TheTrouve]

decent video goes somewhat into degree level optoelectronics, much more clearly presented than in my lectures..

[@nycbearff]

I think any young person watching this will clearly understand Dr. Lancaster's excitement and enthusiasm for her work, and the fact that ultra intense lasers are astonishing instruments which open up astonishing possibilities in nuclear physics. For a lecture like this, in this context, what she delivered was EXACTLY what was needed. With her enthusiasm and joy in her work, how could she not inspire younger people, including young women, to get into scientific research? She so clearly loves it and has so clearly prospered in it. The people below who objected because they didn't find the lecture informative enough, or well organized - well, it was a short lecture about an incredibly complex field. It couldn't have been informative enough about the details of laser technology, no matter who gave the lecture. I found it very impressive.

Using the spectrometer on the white light, you could see that it has the characteristics of an white led. There's a large peak at blue and a broader peak for the phosphor which absorbs some of the blue and re-emits a yellowish light. The combination of the two appears to us as white.

[@NigelTolley]

Possibly. But it's also possible it was a halogen incandescent bulb. We would need to see the wavelength scale to know if it was anything near a black body.

Fusion science has progressed far beyond this talk in 2015 and now in Apr 2019 we have Tokomak Energy producing 15 million C without using lasers in a small scale-able reactor and will soon produce 100 million C. This would be the bottom end of temps necessary for a fusion reaction. Problem with these laser induced target fusion reactions is the destruction of the target in a burst of fusion. Target gone, fuel gone and reaction ends. The fuel is the same though so much is learned about fusion with these experiments. Kate's excitement and her understanding of these exotic physics is appreciated.

@ She keeps glancing down, but she is most often facing and looking straight forward when she does it. The laptop on the desk is significantly off to the right. She is only looking at the laptop when she is manually switching between slides and when she refers to a slide. At 15:55 and 18:48 she steps back and you can clearly see the laptop has the slide that is up on the screen displayed with no other windows open. It appears that the laptop is only for slide generating, so she is actually running the display for her talk while she does it. It probably helps her keep her place, but she is basically doing the presentation from memory.

Figuring that out is what funds the research. You can use those lasers to reduce a whole neighborhood of California homes to white ash and melt the aluminum wheels off a car sitting in the middle of a concrete driveway as though they were icecream bars while leaving the leaves on many of the trees between the rectangular piles of white ash. Added: They included more wavelengths than lasers though. Now they're finding they have to replace underground steel reinforced concrete pipes. The rebar got too hot.

Great lecture and lecturer. I missed the one part in the earlier talk how laser light is made coherent

[@llibressal]

She was referring to Temporal Coherence which is to say that the light waves are in step with each other. This being caused by the majority of light being amplified are the light waves that oscillate as a function of the oscillating cavity distance. .....or at some sub-multiple of that distance.

[@K3Flyguy]

As I understand the easiest but certainly not inxpensive way to coherent the laser light is that need a very large Flux Capacitor tied in harmonic syncrocity to the crystal specific light fractial division modulation inverters. If you can achieve syncrocity at that point, the cascading plasma fall will usually cohert without further manipulation. But it's pretty touchy, as we all know alighning light is akin to herding cats....
