摘　　要：基于二能级原子暗压缩态的制备方案,对多能级原子系统暗压缩态的产生机理进行研究,并提出一个如何在多能级原子系统中制备压缩态的方案。结果表明,在Lamb-Dicke近似下,考虑边带冷却效应就可以将多能级原子冷却至最低最子态;通过选择合适的入射光中心频率,利用多能级原子系统同样可以激光冷却被俘获的原子,并导致暗压缩态的出现。Based on the scheme for generation of dark squeezed states for two-level atoms proposed by J. I. Cirac et al., the generation principle of dark squeezed states for multilevel atoms is investigated in this paper. It has been shown that for multilevel atomic systems, laser cooling can also be conducted on trapped atoms to generate dark squeezed states. Consequently, a scheme for generation of squeezed states for multilevel atomic systems is put forward.
