摘要：

We study effects of rapid spin exchange interaction between K and Cs spins in a K-Cs spin exchange hybrid optical pumping system. The behaviour of the atom spins directly pumped by laser light is investigated. The results show that the electron spins of the K atoms are coupled to the electron spins of the Cs atoms through spin exchange interaction. The K and Cs spins are aligned in the optical pumping system. In the experiment, we measured the Larmor precession frequency of the K atoms and found it to be approximately equal to that of the Cs atoms.
