Laser pioneers win Nobel Physics Prize

Three scientists on Tuesday won the Nobel Physics Prize, including the first woman to receive the prestigious award in 55 years, for inventing optical lasers that have paved the way for advanced precision instruments used in corrective eye surgery. Arthur Ashkin of the United States won one half of the nine-million Swedish kronor (about $1.01 million or 870,000 euros) prize, while Gerard Mourou of France and Donna Strickland of Canada shared the other half. Strickland is just the third woman to win a Nobel Physics Prize since it was first awarded in 1901, while Ashkin, 96, is the oldest person to win a Nobel, beating out American Leonid Hurwicz who was 90 when he won the 2007 Economics Prize.
