Wings was one of the first bands in the 1970s to do stadium tours, as well as Led Zeppelin. We had all the most up-to-date equipment from monitor systems to a laser light show and that was like the biggest, most awesome experience for me.
My PhD project was actually doing something that required a high-intensity laser. It was supposed to work in a way that many, many photons of light would interact with an atom all at the same time.
We proved that we could increase laser intensity by orders of magnitude. In fact, CPA led to the most intense laser pulses ever recorded. Our findings changed the world's understanding of how atoms interact with high-intensity light.
What the ultrafast laser does is that because it doesn’t have to just cut from the surface, it’s only at the intense focal point that it does this damage where the electrons come off the atoms, you could actually put your laser and scan it over your cornea and it would cut underneath that.
Gérard Mourou, who was my PhD supervisor, dreamed up the idea of increasing laser intensity by orders of magnitude. He did it while he was on a ski trip with his family. He probably shouldn’t have been thinking about lasers.
Because the high-intensity pulses are short, the laser only damages the area where it's applied. The result is precise, clean cuts that are ideal for transparent materials.
When I want to quickly take a measurement, I use my Stanley Laser Distance Measurer. You just put it on the wall, and it shoots a laser and instantly tells you the exact distance to the other wall within a fraction of an inch.
There are relatively few experiments in atomic physics these days that don't involve the use of a laser.
