摘　　要：This paper theoretically advances a new method to establish population inversion between energy levels of pure 87Rb atom without buffer gas driven by appropriate laser fields. With the help of density matrix equation and numerical computation tool, the lasing dynamical behavior of 87Rb atom with population inversion in a cavity is demonstrated. The detailed properties of this lasing dynamic behavior and the atom-cavlty coupling with photon are also discussed. This method can be extended to other alkali atoms.

关 键 词：Alkali atomic vapor Population inversion Atomic-cavity coupling.
