Trio of scientists wins Nobel Prize in Physics for laser physics
Royal Swedish Academy of Sciences has announced the Nobel Prize in Physics 2018 for groundbreaking inventions in the field of laser physics. The prize is shared between 3 scientists, with one half to Arthur Ashkin, Bell Laboratories, Holmdel, USA and the other half jointly to Gérard Mourou, École Polytechnique, Palaiseau, France University of Michigan and Ann Arbor, USA and Donna Strickland University of Waterloo, Canada.
Arthur Ashkin invented optical tweezers that grab particles, atoms, viruses and other living cells with their laser beam fingers. This new tool allowed the use of radiation pressure of light to move physical objects. He succeeded in getting laser light to push small particles towards the centre of the beam and to hold them there.
Gérard Mourou and Donna Strickland paved the way towards the shortest and most intense laser pulses ever created by mankind. Using an ingenious approach, they succeeded in creating ultrashort highintensity laser pulses without destroying the amplifying material.
