摘要 We report experiments on the observation of the ^1S0-^3P0 transition spectrum of ^88Sr in the Lamb-Dicke regime.After going through a two-stage magneto-optical trap(MOT),88 Sr cold atoms with number of about 1 × 10^5 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 ^3P1 state mixing into ^3P0 state, the spectroscopy of the1S0-3P0 transition with a linewidth of 180 Hz is detected.
