中文摘要：
提出了一种构建可囚禁与操控三种冷原子或冷分子样品的光学三阱组的新方案，该方案采用常用的液晶空间光调制器作为分光器件，分光调制函数类似于二元相位光栅；对提出的方案进行了模拟实验，并研究了从光学三阱到单阱的双向演化过程。该光学三阱的模拟实验结果与理论方案相符，三阱的操控性好，有利于三种不同的冷原子或冷分子样品的装载与操控等相关实验研究。
英文摘要：
A novel scheme based on light diffraction to generate a triple-well optical trap for trapping and controlling triple-species samples of cold atoms or molecules is proposed. Specialized phase modulation similar to binary phase-grating is implemented by a diffraction device of liquid crystal spatial light modulator （LC-SLM）. A continuous and reversible evolution between single-well trap and triple-well trap is investigated. Corresponding experiments are performed and the results are in agreement with theories. The results show that the proposed scheme has a controllability advantage, which is beneficial to load and control triple-species samples in cold atoms or molecules experiments.
