摘      要:We report on a research of the loading of ultracold sodium atoms in an optical dipole trap,generated by two beams from a high power fiber *** effects of optical trap light power on atomic number,temperature and phase space density are experimentally investigated.A simple theory is proposed and it is in good accordance with the experimental results of the loaded atomic *** a general estimation,an optimal value for each beam with a power of 9 W from the fiber laser is *** results provide a further understanding of the loading process of optical dipole trap and laid the foundation for generation of a sodium Bose–Einstein condensation with an optical dipole trap.
