摘要
用数值积分方法求解了在圆柱坐标中的横向多模菲涅尔 (Fresnel)积分方程 .在初始复数光场振幅取均匀分布和随机分布的条件下对圆形球面共焦腔、稳定腔和平面腔的TEMn0 模进行了计算分析 .计算结果表明 ,球面腔单一模的数值结果同解析解的结果符合较好 。
Fresnel integral equations of the transverse multimode are solved by the numerical integration method in the cylinder coordinate. Under the initial conditions of the uniform and random distribution given respectively for the complex light-field amplitude, TEM n0 modes of the confocal and stable cavities with circular mirrors of spherical surfaces as well as the plane cavity with circular mirrors are computed and analized. Computational results indicate that the numerical results of single mode for spherical cavity coincide with the analytical results. The results of the multimode not only conform to the behavior of the multimode space distribution, but also show that those of the fundamental mode dominate.
