Strickland and Mourou's technique, called chirped pulse
amplification (CPA), became standard for high intensity lasers.

amplifications," Optics Communications, vol.
In all cases the results indicate that comparing an unchirped with a chirped pulse
of the same energy, a lesser fraction of energy is available for soliton formation in the chirped case.
A configuration based on the concept of chirped pulse
amplification is used for SNR enhancement in a [phi]-OTDR sensor as reported in .
Introduced in this work, is the second scenario that combines the chirped pulse
microwave generation and optical beam steering.
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.
Of this amount, $3 million is provided for continued development of the petawatt laser at the University of Texas at Austin; $1 million is provided for an optical parametric chirped pulse
amplifier upgrade and associated operations of the short pulse laser at the University of Nevada, Reno; $1 million is provided to the University of Nevada, Reno to continue its collaboration with Sandia National Laboratories on highly diagnosed studies of exploding wire arrays and implosion dynamics; and $1 million is provided for research using the Z-Beamlet laser at Sandia National Laboratories under the Z-Petawatt Consortium...."
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
The chirped pulse
inherently requires more processing.
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.
This consideration explains why the positive chirped pulse
emits the DW later, or the negative chirped pulse
emits the DW earlier compare to the case of unchirped pulse.
