Preliminary progress of the state preparation with a new optical pumping method in a cesium atomic fountain clock

Abstract

In this paper, a new optical pumping method, redistributing the atom populations among the Zeeman magnetic sublevels of the ground state |F=3> is proposed as the state preparation process to improve the signal to noise ratio (SNR) of the atomic fountain clock with a larger atom population on the |F=3, mF=0>clock state. A preliminary experimental result of state preparation efficiency exceeding 60% is obtained on the NIM6 cesium (Cs) fountain clock.
