摘　　要：研究以原子谱线作参考的半导体激光器的频率锁定系统，在精密控制半导体激光器的工作温度和工作电流的基础上，利用８５Ｒｂ的Ｄ２线的一次微分信号对ＬＤ的频率进行锁定。锁定后ＬＤ的频率最大变化为１０ＭＨｚ／３ｈ，平均取样时间１０ｓ，用Ａｌａｎ方差估算ＬＤ频率稳定度为１０－９。This psper described a laser diode frequence stabilization system composed of a precisely temperature control system and a operating current control system of the laser diode.Using the first defferential signal of the resonance line,the operating frequence of the laser diode can be locked to D2 line of 85 Rb.The measurement results show that the frequence stability evaluated by Allan variance is 10-9 order for 10 seconds sampling time.
