使用双折射晶体成功实现了从平行线偏振到正交线偏振的偏振态转换，用于双模Nd：YVO4微芯片激光器的两个纵向振荡模式。激光器在垂直线偏振态同时发射两个纵向振荡模式，频率差为101 GHz。在实验中，表明通过使用17 mm长的LiNbO3双折射晶体，可以通过在两个振荡模式之间提供π rad的相位延迟差来几乎完美地转换两个振荡模式的偏振状态。用一对波片消除了残余的椭圆分量。
Polarisation‐state conversion from parallel linear polarisation to orthogonal linear polarisation was successfully demonstrated using a birefringence crystal for the two longitudinal oscillation modes of a dual‐mode Nd:YVO4microchip laser. The laser emitted two longitudinal oscillation modes simultaneously in the vertical linear polarisation state with a frequency difference of 101 GHz. In the experiment, it was shown that by using a 17‐mm‐long LiNbO3birefringence crystal, it was possible to almost perfectly convert the polarisation state of the two oscillation modes by providing a π‐rad difference in phase retardations between the two oscillation modes. The residual elliptic component was eliminated using a pair of waveplates.
