对横向塞曼双频激光器理论模型的建立及激光器参数的优化设计进行了研究,建立了连续激光器稳态工作时的激光阈值条件,得到了频率差与磁场、腔长之间的关系。选用激光管腔长为150 mm时,所加磁场应在0.03 T左右,磁场电流为1.3068 A,而管子的损耗为0.032,此时频差为1.3719 MHz。通过对理论数据的计算分析得出,为了提高频率稳定性,应合理选择磁场强度B并选定稳定性和均匀性很好的磁性材料。
The establishment of the theoretical model of the transverse Zeeman dual-frequency laser and the optimization design of the laser parameters are studied. The laser threshold conditions are established for the steady-state operation of the continuous laser, and the relationship between the frequency difference and the magnetic field and cavity length is obtained. When the laser tube length is 150 mm, the applied magnetic field should be about 0.03 T, the magnetic field current is 1.3068 A, and the tube loss is 0.032, at this time the frequency difference is 1.3719 MHz. Through the calculation and analysis of the theoretical data, it is concluded that in order to improve the frequency stability, the magnetic field strength B should be selected reasonably and the magnetic material with good stability and uniformity should be selected.
