概要

In high-energy short-pulse laser facilities, the output energy is mainly limited by the size and damaging threshold of compression gratings. Mosaic gratings are an important way to obtain large-aperture gratings. The precision adjustment system designed for a high-energy picosecond laser facility mosaics two planar diffraction gratings. The system has a 9-dimension automatic precision adjustment mechanism and can satisfy the adjustment requirement of the relative positions of two gratings and the position of the whole grating. Based on the stability test, damping material is applied to reduce the dynamic response of the system and improve stability of the mosaic gratings in a long period. After taking the measure, the angle drift in X- and Y-directions is reduced and the specified stability requirement can be met.
