摘　　要：为了探究定向棱镜谐振腔激光模式分布情况,通过连续利用反射系统的光线矢量的反射定律,推导出具有二面角误差的角锥棱镜相位模型,首次创新性地建立了定向棱镜腔的光场数学模型,并运用FO X-LI的理论,研制了一套求解各种腔形的稳态模的场分布软件。用这套软件模拟出了定向棱镜谐振腔自再现模的分布。同时,针对免调试固体激光器(定向棱镜腔)进行实验,将模拟所得结果与实际激光器的输出近场、远场光斑,以及与光束质量分析仪检测分析结果进行了对比,取得了较好的效果。In order to develop a field distribution program that resolves the model of stable resonator any cavity,the phase model of the cube comer prism is established using continuously the law of reflection of ray vector. A mathematical model of the oriented prism laser field distribution is developed at first. A field distribution program that resolves the model of stable resonator in any cavity is developed. And the modes of stable resonator consisting of directional prism are investigated with FOX-LI iterative method. The amplitude and phase distributions of the output mirror are presented.In the experiment,the avoidance adjust solid state laser is used. Both the experimental results about the output near-field speckle of laser, far-field speckle of laser and the result from the laser beam quality analyzer are compared with 3-D numerical simulation.The simulation results are in agreement with experimental results.A good effect is obtained in practical application.
