摘要
We propose a method for laser cooling two-valence-electron fermionic atoms.Our protocol employs resolved-sideband cooling on the stimulated Raman transition between the two magnetic sublevels(m=F and m=F−1)of the ground state with total angular momentum F.The optical pumping from m=F−1 to 1P1 are used to decouple atoms in the m=F−1 state.We calculate the Raman coupling generated by an engineered optical lattice.The result shows that it is possible to laser cool the two-valence-electron fermionic atoms to the ground state.The atoms in the ground state provide a new system for quantum optics.
