摘要

基于热透镜效应和球差效应同时存在的客观事实,建立了光束质量因子M2与热透镜焦距和球差的内在理论关系,准确地分析了热透镜焦距和球差共同作用下的光束质量变化。实验利用哈特曼-夏克波前传感器对LD端面抽运Nd∶YVO4晶体的相关波前信息进行重构,进而对比光束质量因子M2的实验数据与理论分析结果,证明光束质量在热透镜焦距和球差共同影响下逐渐减弱,验证了此模型的可行性,为固体激光器的优化设计和实验研究提供了参考。

Abstract

Based on the objective fact that the effect of thermal lens and the influence of spherical aberration coexist, the intrinsic theoretical relationship between the beam quality factor M2,the thermal focal length and spherical aberration is established, and the beam quality change under the combined effect of the thermal focal length and the spherical aberration is more accurately analyzed in addition. In this experiment, the Hartmann-Shack wavefront sensor is used to reconstruct the related wavefront information of the Nd∶YVO4 crystal by LD end-pumped. The experimental data of the beam quality factor M2 are compared with the theoretical analysis. Furthermore, under the influence of the thermal focal length and the spherical aberration, the gradual attenuation of the beam quality is proved. The feasibility of this model is finally confirmed. The above conclusions provide the reference for the optimal design and experiment of solid-state laser.
