Narrow-linewidth cooling of 6Li atoms using the 2S-3P transition

We report on a narrow-linewidth cooling of Li-6 atoms using the 2S(1/2) -> 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 x 10(9) atoms with a temperature of 58 mu K. Furthermore, we demonstrate a high efficiency magnetic transport for Li-6 atoms with the help of the UV MOT. Finally, we obtain 8.1 x 10(8) atoms with a temperature of 296 mu K at a magnetic gradient of 198 G/cm in the science chamber with a good vacuum environment and large optical access.
