We report the experimental realization of new stable three-dimensional schemes for trapping neutral cesium atoms in a vapor cell that use either two or four Gaussian laser beams. Probe-beam absorption is employed to characterize both types of trap, and densities of 2 x 10(8) and 1 x 10(10) cm(-3), respectively, are measured for the two-and four-beam traps. The two-beam trapping mechanism combines a longitudinal magneto-optical force with a transverse spontaneous radiation pressure force associated basically with the beam geometry. This theoretical analysis compares well with our experimental observations.
我们报告了在蒸汽室中使用两束或四束高斯激光束捕获中性铯原子的新型稳定三维方案的实验实现。采用探测光束吸收来表征这两种类型的阱,对于两束和四束阱,分别测量到的密度为2×10⁸和1×10¹⁰ cm⁻³。两束光捕获机制将纵向磁光力与基本上与光束几何形状相关的横向自发辐射压力力相结合。这一理论分析与我们的实验观察结果吻合得很好。
