Physicist Explains Lasers in 5 Levels of Difficulty

Rating: 4.0; Vote: 1
Donna Strickland, PhD, winner of the 2018 Nobel Prize in Physics and a professor at the University of Waterloo, is challenged to explain lasers to 5 different people; a child, a teen, a college student, a grad student, and an expert
Date: 2022-07-06

This is my second least favorite explanation so far. Her explanations are good and her achievements are unarguably great, but it becomes very clear when talking to the grad student and colleague that she just wants another Nobel Prize and doesn't really bother with the practical applications. It's not that it wasn't a great talk, but it could have been MUCH better with another expert who has plans beyond reaching a Watt goal

7: 50 WAIT so star wars laser bolts ARE a thing, just that you wouldnt be able to see them?
And all these years people said star wars lasers arent lasers because lasers are a continous beam.
So much for that eh!

She really smart but not as good at - Dumbing down- her info and listening to the younger people responses. Not a bad thing just basing it off some other the other guest. Still very interesting.

If you make the laser light go around in a circle so it cant -escape-, does it stay in the ring even if you remove the flashlight thing? Can you cage it to go around and around for forever?

Me reading the comments section: -yeah that 12 year old was smart--
Me trying to watch the video again: -oh God I don-t understand what she-s talking about, what did I just miss! -

Can someone explain to me how, in a chirped pulse, the red wavelength moves faster than the other wavelengths? Shouldn't they all be moving at the speed of light > c?

-So have you had much exposure to lasers yet? -
-Well I've had laser eye surgery. And I've watched high-powered lasers do their stuff in Star Wars and Battlestar Galactica. -

At some point in this video a man and woman started speaking Greek and no one informed me that I was going to have to learn a foreign language to watch a Wired video -

Photon Torpedos are antimatter bombs, they do not use lasers in any sense. Seems he will not win the nobel prize in understanding Star Trek any day soon: P

Ah, I see the application to be a fully fledge professor going well and got it.
Well, I doubt they would refuse when you put Nobel laureate on it,
