New grating compressor designs for XCELS and SEL-100 PW projects
Efim Khazanov
Abstract:The problem of optimizing the parameters of a laser pulse compressor consisting of four identical diffraction gratings is solved analytically. The goal of optimization is to obtain maximum pulse power, completely excluding both beam clipping on gratings and the appearance of spurious diffraction orders. The analysis is carried out in a general form for an out-of-plane compressor. Two particular "plane" cases attractive from a practical point of view are analyzed in more detail: a standard Treacy compressor (TC… Show more
