This year's Nobel Prize in Physics has been "split" — with one half going to Arthur Ashkin, an American who won for his work with optical tweezers, while Gérard Mourou of France and Donna Strickland of Canada share the other half for work in generating high-intensity ultrashort optical pulses.
Together, their achievements mark groundbreaking achievements in the field of laser physics.
"This year's prize is about tools made from light," said the Royal Swedish Academy of Sciences in Stockholm in its announcement on Tuesday.
