Groundbreaking Inventions In The Field Of Laser Physics: Groundbreaking Research #001

Laser light can be stretched, amplified, and then compressed to create strong, short pulses of energy. Image by Johan Jarnestad/The Royal Swedish Academy of Sciences

Hello there, a few days ago, I asked you guys about your views on me starting a series on researches and I received a lot of encouragement. Here is the first post of this series —


So in this post I will be tell you about the research which gifted the researchers a noble price.

So The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2018 “for groundbreaking inventions in the field of laser physics” with one half to Arthur Ashkin, Bell Laboratories, Holmdel, USA “for the optical tweezers and their application to biological systems” and the other half jointly to Gérard Mourou, École Polytechnique, Palaiseau, France and University of Michigan, Ann Arbor, USA and Donna Strickland, University of Waterloo, Canada “for their method of generating high-intensity, ultra-short optical pulses.” Ah man, now this is actually ground breaking. By the way when I first saw this, my reaction was something like this —

giphy

I mean this changes everything!!!!!

Arthur Ashkin invented TWEEZERS which can grab thing as small as an atom!

As every product, these tweezers weren’t that good in the start, a major breakthrough came in 1987, in this year he was successfully able to pick living bacteria!! Gérard Mourou and Donna Strickland paved the way towards the shortest and most intense laser pulses ever created by humankind!!!

The Science behind the laser pulses

Using an ingenious approach, they succeeded in creating ultrashort high-intensity laser pulses without destroying the amplifying material. First they stretched the laser pulses in time to reduce their peak power, then amplified them, and finally compressed them. If a pulse is compressed in time and becomes shorter, then more light is packed together in the same tiny space — the intensity of the pulse increases dramatically.

Man, this is complicated!!


This is still quite a new thing and the innumerable areas of application have not yet been completely explored. This invention has opened a whole new gate in the field of Laser Physics.

The Laureates:

  • Arthur Ashkin, born 1922 in New York, USA. Ph.D. 1952 from Cornell University, Ithaca, USA.
  • Gérard Mourou, born 1944 in Albertville, France. Ph.D. 1973.
  • Donna Strickland, born 1959 in Guelph, Canada. Ph.D. 1989 from University of Rochester, USA.

Prize amount: 9 million Swedish krona, with one half to Arthur Ashkin and the other half to be shared between Gérard Mourou and Donna Strickland.


If you come across an interesting research like this one, please contact me on radthepoet@gmail.com. If I find it really good, I will credit you for giving me the idea and post it on this blog.
