| 摘 要： | 本文从理论上研究了在外加横向均匀磁场作用下双模气体激光器输出光的偏振特性。用导出的双纵模偏振参数运动方程,计算了双模He-Ne激光器632.8nm谱线的偏振参数。当外加磁场大于某值时,可获得高偏振度的线偏振光输出。理论与实验结果相符合。

| Abstract: | The polarization properties of the output light of two-mode gas lasera ffected by external transverse uniform magnetic field is theoretically investigated. The calculation is given for the polarization paramaters of two-mode He-Ne laser at 632. 8nm with the motion equations deduced for the polarization parameters of two longitudinal modes. The linear polarization output light with high polarization degree is obtained as the strength of the external magnetic field is beyond the threshold value and the experimental results are consistent with the theory. |
