Closed-loop beam quality control for MOPA solid slab laser
摘要
Abstract
This paper introduces the beam characteristics of the MOPA slab laser system, including near-field intensity distribution, spatial character and temporal frequency of wavefront distortion. The deformable mirror with large dynamic range and high spatial resolution was developed. The adaptive optics closed-loop correction system was designed to complete the closed-loop control of the whole propagation process of high power beams. The value of β of beam quality has been improved from 7. 4 to 4. 06. According to the residual error of the closed-loop wavefront correction, the beam quality of the MOPA might be further improved.关键词
