摘要：

A numerical method is presented to study the laser beam distortions and their influence on the interference patterning after propagation through an optical chirp pulse amplification (CPA) system. This study is based on numerical simulation using the ray-tracing model from Optica module of MATHEMATICA and it relates the behavior of the distorted beam in terms of spatial distortions in case of user-induced misalignments in single-grating stretcher-compressor system. It was shown that this effect can be used both to control the femtosecond laser interference pattern design and to improve the quality of the CPA beam profile for ultra-fast micro and nano-patterning experiments using multiple CPA laser beams.
