| 摘 要： | 提出了一种利用单束平面光波照射由液晶构成的二元相位板与透镜组合系统形成可控制光学八阱的新方案;讨论了方案中可控制光学八阱从八阱到四阱、双阱或单阱的双向演化过程。研究表明,通过改变液晶空间光调制器的调制相位分布即可实现从光学八阱到四阱、双阱或到单阱的连续双向演化。探讨了光学八阱在原子分子光学等方面重要的可能应用。

| Abstract: | we expound a novel scheme to form a controllable eight-well optical trap by using an optical system of a binary-phase plate composed by liquid crystal and a lens illuminated by a plane light wave.We discuss the bidirectional evolution process of the optical trap from eight-well to four-well,double-well or single-well.The result shows that the proposed eight-well trap can be continuously changed into a four-well,double-well or single-well trap by changing the brewage phase distributing of liquid crystal room... |
