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...

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.

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.

Time flew by so fast! Dr. Lancaster gave a great presentation.

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.

All that stuff is absolutely amazing, refreshing change from most heavy mathematical talks about science

Thank you Kate for a very interesting talk.

Thank you Ri for another great video!

Around 1963 we had a school trip to the RI for a lecture on lasers, before most people had heard of them. We saw a ruby laser emit a pulse of infrared and burn some carbon paper. How things have changed in my lifetime!

Thanks Dr. Kate Lancaster for this valuable lecture!

Great talk. A lot of information here. My first job was for a company that made xenon lasers so I know about the partial mirrored end cap. They also bought YAG LASERs, a intense white light lamp that pumped a ruby crystal. They had a Q switch in them also. Cool stuff. That was in the late 70's

Wow, thanks for this wonderful explanation of lasers and fusion.

Wonderful lecture; I really enjoyed this. It's so nice to see someone who's really excited about her work.

A smart person is one that can take a complicated subject and teach it to a layperson, something I read recently, and Kate can certainly do that. She had an audience of specialist in various sciences, plus a number of young people. The same with those watching her video. Who knew science could be humorous. I enjoyed that hour. Thankyou Kate.

Its wonderful she seems to have a great deal of passion for her work.

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.

Dr. Kate Lancaster; Professor Emeritus Ali Javan of MIT, shortly after 1958, then with Bell Laboratories, submitted his paper on Gas Discharge Helium Neon Laser for publication. And published 1960. Professor Javan's invention, was the World's First Continuously Operating Laser. He graduated from Alborz high School. Consequently, he was at Columbia University, before becoming a professor at MIT. Later, he was given the greatest honor of Emeritus.

Wonderful presentation, I learned a lot! While she was sometimes getting into some nice details, she keeps the story clear (red line), which is impressive actually!

Not sure why people are criticizing her, it was a good talk with something interesting for both laypersons and experts in the field. Sure, she is not the most charismatic speaker on earth, but overall she succeeded in delivering the intended message. What I found very interesting is that she seemed more comfortable while explaining the more technical slides later in the talk compared to the earlier, more basic slides.
