Three scientists have been awarded the 2018 Nobel Prize in physics for creating tools from light, 2018
Nobel Prize in physics, 2018 has been awarded to three scientists, including one woman, for evolving the science of lasers and forming enormously useful tools out of laser beams.
Physics Nobel Prize won by Arthur Ashkin, Gérard Mourou and Donna Strickland
American, Frenchman and Canadian share 9m Swedish kronor (£770,000) prize for work in laser physics
In laser physics Nobel Prize has been won by Arthur Ashkin, Gérard Mourou and Donna Strickland –
American, Frenchman and Canadian share 9m Swedish kronor (£770,000) prize for their work.
In a telephone interview with the Royal Swedish Academy, Strickland said she was unaware only two women had won the prize before her. She was quite unaware.
Surprisingly, Strickland is the third woman fairly to have ever won the Nobel Prize in physics. 55 years ago Maria Goeppert-Mayer won for her work on atomic structure in 1963, and her predecessor was Marie Curie awarded noble for her work on radioactivity 1903. Noble awarded didn’t knock any woman’s door until 2018.
Strickland was quite unaware only two women had won the prize before her, the amazing view reveals in a telephone interview with the Royal Swedish Academy.
“We need to celebrate women physicists because we’re out there, and hopefully in time it’ll start to move forward at a faster rate. I’m honoured to be one of those women,” said Donna Strickland when she has won the noble prize in Physics. Donna exclaimed grabbing the prestigious prize.
In accordance with the scientist and excerpt Royal Swedish Academy from Ultra-sharp laser beams make it possible to cut or drill holes in various materials extremely precisely – even in living matter. Millions of eye operations are performed every year with the sharpest of laser beams.
‘The journal Nature’ reported this weekend that the Royal Swedish Academy of Sciences would explicitly call on future nominators to consider gender, geography and topic for the 2019 prizes.
“Different people were trying to get short pulses amplified in different ways,” Strickland said. “It was thinking outside the box to stretch first and then amplify.”
The trio physicist settled an elegant ground, which they called “chirped pulse amplification.” First they stretched out first the beam with a mile-long fiber optic cable, reducing its peak intensity. Subsequently they amplified the signal to the desired level, before compressing it into an ultra-short, ultra powerful pulse lasting a small fraction of a second.
The method is just as significant to basic research, found the Royal Swedish Academy.
