Abstract :
The integrating sphere is used to generate the diffuse light for cooling atoms. The microwave field is produced in a cylindrical cavity on a TE011 mode. We have realized the microwave interrogation with the pulsed optically pumped (POP) scheme. The Ramsey fringe is demonstrated and some factors to affect the signal to noise ratio (SNR) and the contrast of the fringe are discussed. Optimization of the experimental parameters is still in progress.
