英文摘要	We present a practical method to avoid the mis-locking phenomenon in the saturated-absorption-spectrum laserfrequency-locking system and set up a simple theoretical model to explain the abnormal saturated absorption spectrum. The method uses the normal and abnormal saturated absorption spectra of the same transition 5~2S_(1/2), F = 2–5~2P_(3/2), F' = 3 saturated absorption of the ~(87)Rb D_2 resonance line. After subtracting these two signals with the help of electronics, we can obtain a spectrum with a single peak to lock the laser. In our experiment, we use the normal and inverse signals of the transitions 5~2S_(1/2), F = 2–5~2P_(3/2), F' = 3 saturated absorption of the ~(87)Rb D_2 resonance line to lock a 780-nm distributed feedback (DFB) diode laser. This method improves the long-term locking performance and is suitable for other kinds of diode lasers.; Project supported by the National Natural Science Foundation of China; 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 4; 44204-1-44204-5; 25
