Frequency stability performance of a laser pumped rubidium vapor cell atomic frequency standard

The AC Stark shift (the light shift) is very important in the performance of laser-pumped vapor cell atomic frequency standards. The frequency stability of a compact rubidium vapor cell atomic frequency standard with an AC Stark shift suppression laser pumping method was evaluated. The applications of such a device include serving as primary reference clocks in communication systems such as Stratum 1 reference clocks.
