针对半导体激光器线阵输出光束快慢轴方向光参数积不对称问题,提出并制作了基于直角棱镜片的光束整形器,其具有结构简单紧凑,制作安装容易的特点。通过数值仿真和实验对光束整形器进行了分析,研究表明整形器实现了半导体激光器线阵输出光束的对称化,并且光束经过透镜聚焦后对数值孔径为0.46,直径为200μm的光纤进行耦合,效率为53%。 Aiming at the asymmetry of the optical parameter product in the fast axis and slow axis of the output laser beam, a beam shaper based on a rectangular prism is proposed and fabricated. The beam shaper has the advantages of simple and compact structure, easy fabrication and installation. The beam shaper is analyzed by numerical simulation and experiments. The results show that the shaper achieves the symmetry of the output beam of the semiconductor laser. The beam is focused by the lens and then coupled to the optical fiber with numerical aperture of 0.46 and diameter of 200 μm. The efficiency Is 53%.
