摘　　要：双频激光器频差大小直接影响双频激光干涉仪测量速度,而纵向磁场是制约纵向塞曼激光器频差的主要因素。通过理论分析双频激光器频差与纵向磁场强度之间的关系,得出磁场最优参数,并选用三种型号激光管进行实验验证。实验表明,磁场强度为0.03T时,双频激光器性能达到最优。The frequency difference of the dual-frequency laser directly affects the measurement speed of the dual-frequency laser interferometer,and the longitudinal magnetic field is the main factor restricting the frequency difference of the longitudinal Zeeman laser.This paper theoretically analyzes the relationship between the frequency difference of the dual-frequency laser and the strength of the longitudinal magnetic field,analyzes the optimal parameters of the magnetic field,and selects three types of laser tubes for experimental verification.The result shows that when the magnetic field intensity is 0.03 T,the performance of the dual-frequency laser is optimal.
