摘　　要：一、前言 关于横向塞曼激光器的稳频方法右各种方案。其中采用风扇冷却的方法结构简单，响应快，驱动功率小，因而在国外首先被商品化。但缺点是因采用了风因扇这一机械转动部件，导致寿命较短，且由于有微小的振动及激光管与外界空气直接接触，In this paper,a frepueucy stabilized transverse Zeeman laser controlled by a current of heater wound aroued the laser iube is described. An optimun strueture of the laser tube enclosuer is designed, so as to reach its thermal equilibrium state in the shortest possible time. By means of personal-eomputer controll of heater eurrcnt the frequency stability is 2 ×10^-11 for the integration time of 10C0 se seconds. Furthermore,to increase the frequency stability, two control loops ere used so the enclosure box works under the constant temperature condition.
