| 摘 要： | 从Fox-Li迭代法出发，用光学仿真软件GLAD实现了对平面环形腔的建模。利用此光学模型进行了腔镜倾斜对其本征模式影响的研究，给出了腔镜在两个方向不同倾斜角度下的谐振腔模式光强分布、光强峰值点位置及谐振腔损耗的变化。研究结果表明:腔镜倾斜使平面环形腔模式发生畸变，随着腔面倾斜加大，腔损耗增大，光强峰值点向镜边沿偏移，且腔镜在垂直于腔面方向上的倾斜对振荡模式的影响比腔镜在腔面内的倾斜对振荡模式的影响大。

| Abstract: | Based on the Fox-Li iterative method, a planar ring cavity is modeled with optical simulation software GLAD, to study the effect of mirror tilt on the oscillation mode. The mode intensity distribution, the peak intensity position and the loss of the cavity are presented in the condition of different mirror tilts in two directions. Results show that mirror tilts result in the resonator mode distortion. With the cavity mirror tilt increasing, the loss of the cavity increases and the peak intensity moves to the edge of the mirror. Mirror tilts in the direction perpendicular to the cavity surface have more effect on the oscillation mode than in the direction parallel to the cavity surface. |
