Focusing properties of gaussian beams passing through a bifocal lens
高斯光束通过双焦透镜的聚焦特性
Detailed numerical results for a pgsm beam passing through a bifocal lens are presented . it implies that the degree of polarization is no longer uniformly polarized in general and propagation - induced polarization changes depend on the beam parameters and system parameters , such as beam coherence parameter
通过对双轴透镜系统进行的数值计算表明， pgsm光束光场的偏振不再是均匀偏振，光束的偏振特性与光束参数和光学系统参数有关，不同相关状态下场点的偏振度不同。
