On Tuesday morning, the Royal Swedish Academy of Sciences awarded the 2018 Nobel Prize in Physics to three scientists "for groundbreaking inventions in the field of laser physics." American Arthur Ashkin was awarded half of the Nobel for inventing "optical tweezers and their application to biological systems," while Gérard Mourou of France and Canadian Donna Strickland were jointly awarded the other half "for their method of generating high-intensity, ultra-short optical pulses." Mourou and Strickland created a technique called chirped pulse amplication (CPA), paving the way "toward the shortest and most intense laser pulses created by humankind."
