Observation of 1S0-3P0 transition of bosonic strontium in the Lamb-Dicke regime
Abstract
We report experiments on the observation of the S 0 1 P 0 3 transition spectrum of Sr 88 in the Lamb-Dicke regime. After going through a two-stage magneto-optical trap (MOT), Sr 88 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 P 1 3 state mixing into P 0 3 state, the spectroscopy of the S 0 1 P 0 3 transition with a linewidth of 180 Hz is detected.
