摘　　要：通过解析和数值模拟系统的海森堡朗之万方程的稳态解,研究了Ladder型三能级原子辅助光力学系统的光学响应.结果表明振动镜子和原子系综的稳态行为与弹簧的劲度系数和经典泵浦场的拉比频率有关.随着劲度系数的减小和拉比频率的增大,腔内原子系综和整个光力学系统将呈现多稳现象,并且不同频域对应稳态解的个数有所不同.因此,可以通过改变泵浦场拉比频率和弹簧劲度系数来控制系统的稳态响应.研究结果在量子信息处理和精密测量等领域具有潜在的应用价值.The optical response of a hybrid system,where a Ladder-type three -level atomic ensemble was confined in a optomechanical microcavity with an oscillating mirror in one end, was investigated by solving the Heisenberg-Langevin equations analytically and numerically. The results show that the steady-state behaviors of the oscillating mirror and the atomic ensemble relate to the elastic coefficient of the spring and the Rabi frequency of the classical pump field, As the elastic coefficient decreases and pump Rabi frequency increases the atomic ensemble and entire optomechanical system will present multiple steadystate solutions with different steady-state numbers in different frequency domains. Therefore, the steady- state optical response of the system could be controlled by manipulating the Rabi frequency of the classical pump field and the spring elastic coefficient. These results may have potential applications in the area of quantum information processing and high-precision quantum measurement.
