Trio win Nobel Prize for work with lasers

STOCKHOLM—Three scientists from the United States, Canada, and France won the Nobel Prize in Physics today for work with lasers described as revolutionary and bringing science fiction into reality.

One of them, Arthur Ashkin of Bell Laboratories in New Jersey, entered the Nobel record books by becoming the oldest laureate at age 96.

Donna Strickland of the University of Waterloo in Canada is the first woman to have won a Nobel in three years, and is only the third to have won for physics.

Frenchman Gerard Mourou of the Ecole Polytechnique and University of Michigan shares half the prize's nine-million kronor ($1.01 million) with Strickland; Ashkin gets the other half.

Sweden's Royal Academy of Sciences, which chose the winners, said Ashkin's development of “optical tweezers" that can grab tiny particles such as viruses without damaging them realized "an old dream of science fiction using the radiation pressure of light to move physical objects.”

Strickland and Mourou, meanwhile, helped develop short and intense laser pulses that have broad industrial and medical applications, including laser eye surgery.

The academy said their 1985 article on the technique was “revolutionary.”

Strickland's award is the first to have gone to a woman in physics since 1963, when it was won by Maria Goeppert-Mayer.

The only other one was Marie Curie in 1903.

“Obviously we need to celebrate women physicists because we're out there,” Strickland said in a phone call with the academy after the prize announcement.

“And hopefully in time, it'll start to move forward at a faster rate, maybe.”

Michael Moloney, CEO of the American Institute of Physics, praised all the laureates.

“It is also a personal delight to see Dr. Strickland break the 55-year hiatus since a woman has been awarded a Nobel Prize in physics, making this year's award all the more historic,” he added.

Moloney credited the work of all three with “expanding what is possible at the extremes of time, space, and forms of matter.”

Yesterday, American James Allison and Japan's Tasuku Honjo won the Nobel medicine prize for ground-breaking work in fighting cancer with the body's own immune system.

The Nobel chemistry prize comes tomorrow, followed by the peace prize on Friday.

The economics prize, which is not technically a Nobel, will be announced Oct. 8.
