摘　　要：本文介绍一种利用分析参考腔与输入激光的位相变化引起光的偏振性质变化,从而产生与激光频率变化相对应的误差信号,并制成了用此误差信号控制可调谐环形染料激光器(801A型)的偏振法稳频器。激光频率长期漂移达1小时58赫芝,短期稳定性(即有效线宽)优于2×10^(-9)。In this paper, we present a method by analysing the change of the properties of the polarized beam which is caused by the phase-change between the reference cavity and input light to provide the error signal corresponding to the change of the laser frequency. We have been made a laser frequency stabrlizer by the polarization technique,which uses the error signal to control the tunable CW ring dye laser（type of 801A）. Now the long-term shift of the laser frequency has been reached 58 MHz per hour, and the short term stability（that is the effective linc width）has an advantage over 2 × 10^-9.
