| 摘 要： | 介绍了双纵模He-Ne激光器的热稳频技术原理，设计了热稳频控制系统，并进行了相关的实验。根据实验结果可知，本热稳频系统实现了将两个纵模频率稳定在增益曲线中心频率对称位置和不对称位置上。根据拍频结果可知，当稳定在对称位置上时，激光器的频率稳定度达10^-10量级；当稳定在不对称位置上、维持频率稳定度10^-10量级时，激光器输出单纵模的功率最高达总功率的80%。

| Abstract: | The principle of thermal frequency stabilization technology of double-longitudinal-mode He-Ne laser is introduced and the control system is designed in this paper. Related experiments were carried on. According to the experiments, the two modes of frequency can be stabi-lized on symmetric and asymmetric positions of the gain curve. According to the beat frequency tests, when the two modes are stabilized on sym-metric position, the frequency stability of He-Ne laser is on the magnitude of 10 ^-10;and when the two modes are stabilized on asymmetric position and the frequency stability maintains on the magnitude of 10^ -10 , the biggest power of single longitudinal mode is 80% of the total power. |
