根据用相位板产生可控制光学双阱的实验方案,制作了具有不同相位差的相位板,测量了不同相位差相位板衍射光强分布和从双阱到单阱演变过程中的衍射光强分布,得到了理论与实验一致的结果.进一步分析实验结果发现:相位差△ψ≠π的相位板,产生非对称光学双阱,在原子光学实验中也有很重要的应用,从而拓展了光学双阱在原子光学实验中的应用范围.

The phase plates with different phase differences were fabricated according to the experimental scheme that used phase plates to generate controllable double-well optical traps. The diffraction intensity distributions of different phase plates and intensity distribution from double-well to single-well evolution process were measured. The experimental results showed good accordance with the theoretical results. Further analysis of the results revealed that the phase plates with △φ≠π can generate asymmetric double-well optical traps. This has important applications in atomic optics experiment and develops their application range.
