Episode 295 - Powerful and precise Lasers - Nobel Prize in Physics ‘18

October 8, 2018

Laser are used in some many things around us from computer storage, discs, communication, medical scanning and even laser surgery. Turning lasers from an expensive tool in the exclusive hands of large laboratories to something people all over the world can simply and easily use required groundbreaking physics. As did turning a laser into a pair of precise tweezers. For that groundbreaking research Arthur Ashkin, Gerad Morou and Donna Strickland won the Nobel Prize in physics in 2018. We find out about lasers, how they're used and how they were made powerful and precise.
