He is six years older than Leonid Hurwicz was when he was awarded the 2007 economics prize.The academy said Mourou and Strickland &quot;paved the way toward the shortest and most intense laser pulses ever created by mankind.&quot;The pair&#x27;s technique, called chirped pulse amplification, has already been adapted to the medical sphere, leading to new advances in corrective eye surgery.Strickland is the first woman to be awarded a Nobel Prize in physics since 1963, when Maria Goeppert-Mayer was recognized for her work on nuclear shell structure.Strickland is also only the third woman to have won the physics prize, which was first awarded to Marie Curie in 1903.
