【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。更多还原

【Abstract】 In order to develop a field distribution program that resolves the model of stable resonator any cavity,the phase model of the cube corner 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.更多还原
