摘要
为了提高面阵二极管激光器侧泵浦板条激光器泵浦光的利用率 ,采用光线追迹的方法 ,通过数字模拟设计出了高耦合效率的波导耦合系统。实验测试结果表明 ,其耦合效率达到 85 %以上 。
In order to increase the coupling efficiency of diode laser arrays side pumped slab laser and efficiently the mode of slab laser, the wave guide coupling system with the high coupling efficiency is designed by means of a ray tracing method. The large end surface of the coupling system is connected with high power diode laser arrays, and the small end surface is connected with the laser slab. The experimental results show that the optical coupling efficiency is 85%, and the output beam from the slab has a uniform profile. The wave guide systems have been used in laser experiment, and the near diffraction limited beam has been obtained in the slab laser.
