Abstract :
The Short- and medium-term stability of traditional rubidium atomic clocks are mainly limited by the light shift effect. Based on the Pulsed Optical Pumping (POP) technique, which can be used to reduce the light shift effect, we present a laboratory prototype of 87Rb maser. With preliminary measurement, the frequency stability of the clock is 1.2×10-12 τ-1/2(τ =1~100s).
