摘　　要：实现了一种可靠而又简单的用Doppler展宽的Zeeman光谱对连续单纵模钛宝石激光器进行稳频的方法。这种方法所需激光输出功率小于1 mW,激光器频率的长期稳定度小于1 MHz/h,且不受激光输出功率起伏的影响,频率锁定点可以在多谱勒展宽范围里随意调节。We have demonstrated a robust and easy frequency stabilization method for Ti:sapphire laser, using Doppler-broadened Zeeman spectrum. In this method, only very weak laser output power (<1 mW) is required, and the experimental setup is relatively simple. A long-time frequency stability of less than 1 MHz/h is achieved. In addition, the stability is not affected directly by the laser output power fluctuation and the frequency locking point could be set arbitrarily in the Doppler-broadened spectral range.
