英文摘要	We present a practical method to avoid the mis-locking phenomenon in the saturated-absorption-spectrum laser frequency -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(2)S(1/2), F = 2-5(2)P(3/2), = 3 saturated absorption of the Rb-87 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(2)S(1/2), F = 2-5(2)P(3/2), F' = 3 saturated absorption of the Rb-87 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.; National Natural Science Foundation of China [11174015]; SCI(E); 中国科技核心期刊(ISTIC); ARTICLE; wangyanhui@pku.edu.cn; 4; 25
