Abstract

This invention relates to one laser super impulse parallel grating adjust method on parallel light grating on compression device. This invention method is of easy operation, high accuracy without space limit between gratings.

Description

technical field [0001] The invention relates to a laser ultrashort pulse compressor, in particular to a method for adjusting parallel grating pairs of a laser ultrashort pulse parallel grating pair compressor. The invention has the advantages of simple operation for adjusting gratings to be parallel, high precision, no space limitation between gratings, and the like. Background technique [0002] Ultra-short and ultra-intense laser science is an important frontier field of science, focusing on the development of ultra-short and ultra-intensive lasers, the interaction between ultra-short and ultra-intense lasers and matter, and cutting-edge basic research in interdisciplinary and related high-tech fields. The ultra-short and ultra-intensive laser system is the basic equipment for research in the field of ultra-short and ultra-intense laser science. [0003] Most of the existing ultrashort and ultraintense laser systems in the world are based on chirped pulse amplification te...
