中文摘要：

一条频率稳定途径基于与一快高精确的波长米连接的一个控制计算机的反馈系统用 intracavity 倾斜调节和调节温度的 etalon 为微秒脉搏钠烽火激光被介绍。钠烽火激光的频率稳定性与循环控制相比并且没有反馈。激光的输出波长与控制技术的反馈循环在 12 h 上被锁到钠 D 吸收线(589.159 nm ) 。作为结果，钠激光指南星被国家天文台的望远镜成功地在 Xinglong 观察。这条途径能也为频率稳定被用于另外的脉搏和连续波浪的激光。

英文摘要：

A frequency stabilization approach is introduced for the microsecond pulse sodium beacon laser using an intra- cavity tilt- and temperature-tuned etalon based on a computer-controlled feedback system connected with a fast high-precision wavelength meter. The frequency stability of the sodium beacon lasers is compared with and without feedback loop controlling. The output wavelength of the laser is locked to the sodium D2a absorption line （589.159nm） over 12h with the feedback loop controlling technology. As a result, the sodium laser guide star is successfully observed by the telescope of National Astronomical Observatories at Xinglong. This approach can also be used for other pulses and continuous-wave lasers for the frequency stabilization.
