【Abstract】 Frequency of diode laser is stabilized by using saturated absorption spectroscopy. High signal-to-noise ratio of differential error signal of saturated absorption spectroscopy is achieved by designing and optimizing the servo loop, thus the sensitivity of frequency locking and long-term frequency stability are improved. This system may be used to the realization of laser cooling and trapping of rubidium atoms.
