摘　　要：利用有源增益薄片近似代替有源腔中的增益介质和采用Ｆｏｘ－Ｌｉ迭代法，我们获得了微型ＤＰＬ的圆形有源介质Ｆ－Ｐ腔的模模模型，同时还分析了腔稳态场的振幅和相位分布分别受腔的菲涅耳数Ｎ和非饱和增益增量△Ｇ影响的情况。数值计算结果与文献报道的实验情况比较一致。By means of substituting approximately active gain sheets for active medium and Fox-Li’s iterative method of successive approximations, an analytical model for transverse modes in an active medium Fabry-Perot resonator with circular mirrors is developed.The study includes computation of field distributions, Fresnel number and unsaturated incremental power gain. Numerical results show an agreement with the experimental results reported recently.
