To ensure the beam quality reach the requirement of high efficiency third harmonic conversion and small focal spot size , the correction of wave - front aberration had to be considered in the design of high power solid - state laser facility 在高功率固体激光系统总体设计中,为了使光束质量满足高效率三倍频和小孔进腔打靶的要求,必须对激光的波前畸变进行校正。
