Resonant gradient force on atom interacting with laser field

Fang, Jianxing, Chen, Xianfeng F., Zhu, Shiqun and Zhang, Rong Resonant gradient force on atom interacting with laser field. Chinese Optics Letters, 1 (2), pp. 122-124.


The gradient force, as a function of position and velocity, is derived for a two-level atom interacting with a standing-wave laser field. Basing on optical Bloch equations, the numerical solutions for the gradient force f_(|_;n) (n = 0, 1, 2, 3, 4, ...) pointing in the direction of the transverse of the laser beam are given. It is shown the higher order gradient force plays important role at strong intensity (G = 64), the contribution of them can not be neglected.
