Abstract

We report a study of a model of a magneto-optical trap (MOT) for atoms 6Li in the field with configuration produced by the counterpropagating elliptically polarised waves, which are in resonance with the optical transition 2S1/2 → 2P3/2 (λ = 670.977 nm). The model takes into account hyperfine splitting of levels inside the natural linewidth of the optical transition. In contrast to a conventional MOT formed by counterpropagating circularly polarised waves (σ + – σ – configuration), the suggested MOT may provide a deeper sub-Doppler cooling of 6Li atoms.

椭圆偏振光波形成的6Li原子磁光阱

本文研究了原子6Li的磁光阱(MOT)模型，该模型是由与光学跃迁2S1/2→2P3/2 (λ = 670.977 nm)共振的反传播椭圆极化波产生的。该模型考虑了光学跃迁自然线宽内能级的超精细分裂。与传统的由反传播圆极化波(σ + - σ -结构)形成的MOT相比，该MOT可以为6Li原子提供更深的亚多普勒冷却。
