Using a Phase Corrector Plate to Correct Static Phase Aberrations in High Power Laser System

摘要

Based on the analysis of phase aberrations in high power laser system, the phase corrector plate is presented to correct the static phase aberration. It can greatly improve the performance of the focal spot and is regarded as the suitable supplement of adaptive optics. In this paper, the performance of phase corrector plate, both continuous structure and multi-steps structure, is analyzed and simulated. The effect of misalignment between the phase corrector plate and the laser beam on the focal spot is also presented and simulated.
