An international group of contributors discuss optical parametric and chirped pulse amplification; ultrafast sources and amplifiers; high power fiber, short pulse, and short wavelength fiber lasers; fiber and nonlinear optics; UV and visible sources; ytterbium, neodymium, mid-infrared, and far-infrared lasers; infrared sources; growth, characterization, and spectroscopy; and advanced concepts and novel architectures.
Lindl said that "indirect, direct, and tetrahedral drive target illumination geometries can be accommodated by the NIP design and advanced technology for compact chirped pulse amplification is being pursued to allow fast ignition on NIP."
Mourou, then at the University of Rochester in New York and now director of Michigan's optical science center, led a team that, to generate high-power laser pulses, invented a technique called chirped pulse amplification. Researchers now have laser systems that produce light in bursts as short as 100 femtoseconds and with peak powers as high as 100 trillion watts.
Arthur Ashkin, Donna Strickland and Gerard Mourou won the 2018 prize for two contributions to laser science, Ashkin for his work on optical tweezers, and Mourou and Strickland for the invention of chirped pulse amplification, a technique to amplify an ultrashort laser pulse up to petawatt levels.
With Mourou's technique, which hecalls "chirped pulse amplification,' researchers reduce the intensity by stretching out a laser pulse--making it last 1,000 times longer--before it enters the amplifying glass.
With chirped pulse amplification, saysMourou, "we can use a system that is 1,000 times smaller.
The 2018 Nobel Prize in Physics has been awarded to three scientists for two discoveries in the field of laser physics: the development of optical tweezers by Arthur Ashkin, and the invention of chirped pulse amplification (CPA), by Donna Strickland and Gerard Mourou.
