Abstract :
In this paper, we propose a new method to reduce the temperature sensitivity of Chip Scale Atomic Clocks. We studied the relationship between RF power and the light shift as well as the relationship between the temperature and the collision shift, and the results are given. It is shown that the frequency shift caused by the change of the temperature can be compensated by the variation of light shift through the adjustment of RF power, in order to reduce the total output frequency shift.
