An efficient Sisyphus cooling and geometric cooling of three level atoms in blue detuned evanescent light wave are discussed, and the kinetics processes of atom cooling in a pyramidal and conical hollow trap is studied by Monte Carlo simulation.

• 讨论了三能级原子在消逝波光场作用下的Sisyphus冷却和几何冷却机制， 通过蒙特卡罗（Monte－Carlo）方法分别模拟了消逝波光场在方锥形势阱和圆锥形势阱两种情况下对原子冷却的动力学过程， 并计算了原子在不同的失谐量、激光功率及消逝波的判断宽度下的冷却情况。
