Abstract
We present a method of aligning a four-grating compressor of optical pulses developed for the multipetawatt OPCPA laser complex PEARL-X under construction at the Institute of Applied Physics of the Russian Academy of Sciences (IAP RAS). The method was successfully used in the compressor of the petawatt laser system FEMTA. The operating planes and the direction of grating grooves were aligned parallel to the vertical axis of rotation by means of silica glass alignment cubes situated on top of the diffraction gratings. Fine alignment of compressor gratings located opposite each other was done by movable mirrors which enabled observing far field images of two beams: mirror-reflected from one grating and reflected from the other grating.
