The Nobel Prize in Physics 2018 was awarded "for groundbreaking inventions in the field of laser physics" with one half to Arthur Ashkin "for the optical tweezers and their application to biologica...
Optical physicists Arthur Ashkin, Gérard Mourou and Donna Strickland have won this year’s Nobel Prize in Physics for “groundbreaking inventions in the field of laser physics.” · Half of this year’s nine-million-kronor (about $1-million) prize goes to American physicist Arthur Ashkin for his invention of “optical tweezers,” lasers that can probe the machinery of life without causing damage. The other half will be split jointly between French physicist Gérard Mourou and Canadian ...
In this work, coherent control of the dynamics of an optical tweezer phonon laser is used to share coherence between its different modes of oscillation, creating a multimode phonon laser....
