Abstract
We report experiments on the observation of the S01 P03 transition spectrum of Sr88 in the Lamb-Dicke regime. After going through a two-stage magneto-optical trap (MOT), Sr88 cold atoms with number of about 1×105 and a longitudinal temperature of 8.4 μK are loaded into a one-dimensional (1D) optical lattice, which is realized with a semiconductor laser at 813.4 nm. Using the magnetic field-inducing P13 state mixing into P03 state, the spectroscopy of the S01 P03 transition with a linewidth of 180 Hz is detected.
