Abstract :
One of the most important physical processes that occurs in Rb frequency standards is the light shift, which depends strongly on the intensity and the optical frequency detuning of the pumping light. This paper presents a method to compensate the light shift by means of two-laser-pumping. The two-laser-pumping schemes will also improve the signal-to-noise ratio since almost all atoms can be pumped to the desired state
