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.
