为了研究基片边缘对激光汇聚原子光学势阱的影响,基于标量光学理论,采用数值计算对基片衍射与否两种情况下,高斯激光驻波场光学势阱进行了仿真,通过三维和截面仿真图充分显示了两种情况下高斯激光光学势阱的异同.详细研究了激光中轴线与基片表面距离、激光束腰和反射镜之间的距离对光学势阱的影响.
In order to study the influence of the substrate edge on the optical potential of laser converging atoms, based on the scalar optics theory, the optical potential of the standing wave field of the Gaussian laser was simulated by numerical calculation of the substrate diffraction or not. The simulation diagram shows the similarities and differences of Gaussian laser optical potential well in two cases.The influence of distance between the laser axis and the substrate surface and the distance between the laser beam waist and the mirror on the optical potential well is studied in detail.
