摘　　要：从光学布洛赫方程出发,对激光驻波场中作用在原子上的光压力进行了求解,求得了轴向光压力和梯度光压力的二阶谐波项的解析解,得到当激光场较强时,光压力的二阶谐波项的作用不再是低强度时的零贡献这一重要结论.From the optical Bloch equations, the force on the atom interacting with a standing-wave laser field is calculated. Then, the solution of second harmonics for the longitudinal light force and gradient light force is obtained. It is shown that the second harmonics for the longitudinal light force and gradient light force play important role for strong laser intensity.
