摘要
针对高斯型随机位相畸变,应用夫琅和费(Fraunhofer)衍射积分研究了畸变光束的聚焦特性和光束质量M2因子,给出了它们随位相畸变特征量变化的近似分析和数值计算结果,可为高功率激光器的设计提供理论依据。
Based on Fraunhofer diffraction integration, we have developed a theory onfocusing characteristics and beam quality of aberrated beam of which the phase aberrationis assumed to be a Gaussian random variable. Both approximate and calculated resultshave been presented. It is applicable in designs of nigh power lasers.
