Abstract

We report on a narrow-linewidth cooling of 6^{6}Li atoms using the 2S1/23P3/22S_{1/2}\to 3P_{3/2} transition in the ultraviolet (UV) wavelength regime. By combining the traditional red magneto-optical trap (MOT) at 671 nm and the UV MOT at 323 nm, we obtain a cold sample of 1.3×1091.3\times10^9 atoms with a temperature of 58 μ\muK. Furthermore, we demonstrate a high efficiency magnetic transport for 6^{6}Li atoms with the help of the UV MOT. Finally, we obtain 8.1×1088.1\times10^8 atoms with a temperature of 296 μ\muK at a magnetic gradient of 198 G/cm in the science chamber with a good vacuum environment and large optical access.
