摘　　要：我们研制的主动稳频连续波可调谐环形染料激光器,其波长范围从5700～6200可以连续调谐;激光频率短期稳定性小于1MHz;长期激光频率稳定性在一个小时之内小于100MHz:并且可以自动连续扫描30GHz 不跳模。论述在环形腔外采用一个高精度、高稳定性的光学参考腔(即为光学鉴频器),将激光频率的不稳定性鉴别出来,通过三路电子学控制系统,对环形染料激光器腔内几个激光频率调谐元件进行反馈控制,并且可以对激光频率进行自动锁定扫描跟踪控制。Laser is now used in many fields of science researches,especially in laser spectroscopy,laser chemistry and isotope seperation. It is required precisly and characteristically for the lasers to op- erate with stable frequency,narrow spectrum range and continously regulated wavelengthes. We have succeeded in researching for and making out an active st- abilized frequency ring dye laser.Its wavelength range is from 5700 to 6200A and can be regulated continously. The short-term stabilization of the laser frequency is no more than 1MHz and its long-term stabilization is less than 100MHz during one hour.The laser automatic scanning range is over 30 GHz without mode-hop. The main theory of stabilization of this kind of laser is based on a high precise interferometer used for detecting the variability of the laser frequency.Depending on three electronic control systems,we take feedback controls on several turnable elements for stabilizing frequ- ency.This laser eletronic control system also uses an automatic loc- king method. This paper gives emphasis on the analysis about the technique of stable laser frequency control system.
