摘要
在ZEAMX软件的非序列模式下利用几何光路的原理,模拟并仿真了一个可压缩1064nm半导体泵浦板条激光器激光光束的准直系统。此系统由两个相互垂直的椭圆柱面透镜组成。30°和15°分别为半导体激光器的快慢轴初始发散角,经过激光准直系统后,板条激光器在快慢轴方向发散角分别为4.4mrad和3.6mrad,达到了设计要求。
In order to compress the 1064 nm semiconductor pumped slab laser beam, a collimation system composed of two mutually perpendicular elliptic cylindrical lenses was designed based on the geometric optical path principle, and the simulation and tolerance analysis were carried out in the non-sequential mode of ZEAMX software.The initial divergence angles of the fast and slow axes of the semiconductor laser are 30° and 15°. After passing the Laser collimation system,the divergence angles of the fast and slow axes of the semiconductor laser beam are 4.4 mrad and 3.6 mrad respectively,meeting the design requirements.
