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.
Obviously, over the history of certainly the last 300 years, it was that men went out and worked, and women stayed home. Yes okay, that’s the way it was. But certainly it isn’t that women weren’t able to do it.
In high school, I was very good in math and physics. I wasn’t good at much of anything else. Some people are good at a lot of things. I don’t know how they choose what to do.
As for me, I want to have fun while I’m working. Now not everyone thinks physics is fun, but I do. I think experimental physics is especially fun, because not only do you get to solve puzzles about the universe or on Earth, there are really cool toys in the lab.
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.
I was very good at math and physics. And that’s all. I can’t do music, art, so there was not a lot of choice for me. I think people should go with their strength and that was my strength.
I still try to make different types of lasers that other people don’t have.
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.
It is understandable that people want to know how it affects them. But as a scientist, I would hope society would be equally interested in fundamental science.
