Three scientists, Arthur Ashkin of the U.S., Gerard Mourou of France and Donna Strickland of Canada, won the Nobel Physics Prize for inventing optical lasers that have paved the way for advanced precision instruments used in corrective eye surgery. Arthur Ashkin won one half of the 9 million Swedish kronor (about $1.01 million) prize, while Gerard Mourou of France and Donna Strickland of Canada shared the other half.
Mr.Ashkin invented optical tweezers that grab particles, atoms, viruses and other living cells with their laser beam fingers. He made this discovery while working at AT&T Bell Laboratories from 1952 to 1991.
Mr.Mourou and Ms.Strickland won for helping develop a method to generate ultra-short optical pulses that are the shortest and most intense laser pulses ever created by mankind. Their technique is now used in corrective eye surgery. Ms.Strickland is the only the third woman to win the Physics Prize.
