摘　　要：从光学布洛赫方程出发,对激光驻波场中作用在一双能级原子上的光压力进行求解,求得轴向光压力的二阶谐波项的解析解,并得到当激光场较强时,二阶谐波项的作用不再是低强度时的零贡献这一重要的结论。From the optical Bloch equations,the force on the atom interacting with the laser field is calculated. Then, the solution of the second harmonics for the longitudinal light force is obtained. It is shown that the second - order longitudinal light force plays important role for strong laser intensity.
