摘　　要：基于TSAG磁光晶体的法拉第效应和Nd∶YVO_(4)晶体的偏振特性,本文研究了一种双路输出的激光器,其激光输出呈线性偏振。未加磁场时,激光器单路偏振输出。当加上磁场后,激光器则成双路偏振输出,且输出偏振角度和功率随磁场强度而变化。随着磁场强度的不断增大,一路光的输出功率不断减小,而另一路的输出功率则不断增大。双路偏振输出激光器可以应用于位移测量、区域环境监测和双光梳测距技术等领域。A dual polarization laser is studied based on the Faraday magneto-optic effect of TSAG and the polarization characteristics of Nd∶YVO_(4).When there is no magnetic field,the laser has only a single polarization output.When the magnetic field is applied,it becomes dual polarization output,and the polarization angle and power of laser vary with the magnetic field intensity.With the increase of magnetic field intensity,one output power is decreasing,while another one is increasing.Dual polarization laser can be used in displacement measurement,regional environmental monitoring,dual-comb ranging and other fields.
