摘要：
解析求解了由四块相同衍射光栅组成的激光脉冲压缩器参数优化问题。优化目标是获得最大脉冲功率，同时完全排除光束在光栅上的遮挡截断和杂散衍射级次的产生。分析针对离面压缩器以一般形式展开。从实用角度出发，更详细地分析了两个特定的平面情况：标准Treacy压缩器（TC）和入射角等于Littrow角的压缩器（LC）。结果表明，在两种情况下LC均优于TC。具体而言，对于160 cm衍射光栅，最优LC设计可为XCELS实现109 PW、为SEL-100 PW实现115 PW，而最优TC设计为两个项目均实现86 PW。
英文摘要：
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) and a compressor with an angle of incidence equal to the Littrow angle (LC). It is shown that in both cases the LC is superior to the TC. Specifically, for 160-cm diffraction gratings, optimal LC design enables 109 PW for XCELS and 115 PW for SEL-100 PW, while optimal TC design enables 86 PW for both projects.
