We report a new design for a polarization-selective laser cavity with birefringent diffractive phase elements. This laser cavity can create two modes with different polarizations and profiles launched separately from two end mirrors. The numerical simulation results show that the constructed laser cavity can successfully generate two orthogonal polarization modes with a uniform circular shaped pattern output from one end mirror and a uniform square-shaped pattern output from another end mirror.
我们报道了一种采用双折射衍射相位元件的偏振选择性激光腔的新设计。该激光腔可以产生两种具有不同偏振和分布的模式，分别从两个端面镜发射。数值模拟结果表明，所构建的激光腔能够成功地产生两种正交偏振模式，一种模式从一个端面镜输出均匀的圆形图案，另一种模式从另一个端面镜输出均匀的方形图案。
