Chirped pulse amplification (CPA), originally proposed by Strickland and Mourou, is a critical enabling technology for creating very short laser pulses with very high peak power. It consists of three optical components: a stretcher, an amplifier, and a compressor. An initial laser pulse of short duration and low energy content is first stretched out in time by the stretcher, resulting in a pulse with longer duration, low energy content, and very low peak power. The pulse is then amplified to increase its energy content without changing its duration in time. The amplified pulse is finally compressed in time in the compressor, resulting in a laser pulse with very short duration and very high peak power. The objective of this work is to develop numerical techniques that enable small-scale grating aberrations in the compressor to be analyzed through high performance computer simulations.
