>> The 2018 Nobel Prize in Physics.>> Breakthroughs in laser pulses and optical tweezers have been recognized with a Nobel Prize. The Physics award was given to scientists Arthur Ashkin, Gerard Mourou, and Donna Strickland on Tuesday. The Royal Swedish Academy of Sciences say the inventions being honored revolutionized laser physics.
Ashkin invented optical tweezers that could grab particles, atoms, viruses, and other living cells. Mourou and Strickland separately created the shortest and most powerful laser pulses ever, the type that are now standard for corrective eye surgery. American Ashkin won half of the prize, Frenchman Mourou and Canadian Strickland will share the other half of the $1 million prize.
Strickland becomes only the third woman ever to win a Nobel Prize for Physics, the last was 55 years ago.
