摘要
提出了一种利用单束平面光波照明二元π相位板与透镜组合系统实现冷原子或冷分子囚禁的可控制光学六阱的方案,计算与分析了该方案产生的光学势阱的光强分布和光学六阱的特征参数、强度梯度及其曲率,讨论了从光学六阱到双阱或到单阱的演化过程,研究表明通过改变二元π相位板上的相位分布,即可实现光学六阱到双阱或到单阱的连续双向演化。
Abstract
We propose a novel scheme to form a controllable six-well optical trap for cold atoms or molecules by using an optical system of a binary π-phase plate and a lens illuminated by a plane light wave. We calculate the intensity distribution of the six-well optical trap and discuss the evolution process of the optical trap from six-well to double-well or a single-well. The result shows that this six-well trap can be continuously changed into a double-well or single-well one by changed the π-phase plate.
