铯原子的三维近共振光学晶格特性的理论研究

摘要

关于一个铯原子的三维近共振光学晶格的详细计算.在三维空间采用不共面的四束光构建一个晶格.根据合场强的分布展开讨论.通过推导,使得在三维空间采用四束光可以避免因相位改变而引起晶格形状改变的理论依据更加充实.%In this study,we have made a detailed calculation of 3-D resonance optical lattice of Cesium atom.We constructed a lattice by means of four non-coplanar beams within a 3-D space.We have made a discussion based on the distribution of the whole field.Our conclusion has reinforced the theoretic basis for the argument that the adoption of four beams in a 3-D space can avoid the change of lattice owing to the change of phase.
