Optimized loading of ultracold Cs atoms in a magnetic levitated optical dipole trap

We presented a comprehensive study of optimized loading of ultracold Cs atoms in a magnetic levitated crossed dipole trap. Moreover, we analyzed the optimized experimental parameters of the dipole laser for the opening time and the power intensity prior to switching on the magnetic field which formed the magnetically levitated dipole trap. The number of atoms as the function of sweep time from distinct laser power intensity to a fixed one is measured. And beyond that, the variation of atoms with the dipole laser power intensity per beam was studied experimentally ranging from 0 W cm-2 to a fixed one for loading the dipole trap, and the number of atoms can be increased up to a maximum of & SIM;1.67 x 106. Our research demonstrates that the 'pre-loading process' plays a crucial role in enhancing the loading efficiency of an optical dipole trap.
