It is proposed to develop a laser cooling theory for multi- state atoms in fully three dimensional light fields. Operator algebra is employed to express the theory in terms of Matrix operations suitable for implementation on a computer. One will obtain the force and diffusion coefficients characterizing the mechanical effects of light and finally simulate numerically the motion of an atom. Numerical experiments will be made for quantitative aspects such as the temperature of the atoms and qualitative features such as possible trapping of atoms in the structures of a standing wave field.

提出了在全三维光场中建立多态原子的激光冷却理论。算子代数是用适于在计算机上实现的矩阵运算来表示理论的。我们将得到表征光的力学效应的力和扩散系数，并最终数值模拟原子的运动。数值实验将用于定量方面，如原子的温度和定性特征，如驻波场结构中可能捕获的原子。
