摘　　要：利用部分相干光的张量ABCD定律,采用解析的方法研究了部分相干的非轴对称高斯-谢尔模(GSM)光束在高斯型光腔内的频谱演化特性,结果表明非轴对称GSM光束的相对频移与振荡的次数以及光腔的参数有关.解析的分析方法避免了已往处理部分相干光频谱演化时采用数值积分所带来的计算冗长的问题,并且适用于任意的傍轴光学系统.The self-consistent solution of partially coherent twisted anisotropic Gaussian Schell- model （GSM） beams in optical resonator and stability condition of resonator is treated analytically by using the tensor ABCD law for partially coherent twisted anisotropic GSM beams. At the same time, analyzed here is the spectral shift of partially coherent twisted anisotropic GSM beams in Gaussian optical resonator. The results show that the spectral shift of twisted anisotropic GSM beams in optical resonator is closely related to the transit times and resonator parameter. It can avoid numerical integral that was commonly used in the previous study of spectral shift problems, and can be applied to any paraxial optical systems.
