Abstract
In this paper, a high sensitive photoassociation spectroscopy of cesium molecular 0g- long-range state close to the 6S1/2+6P3/2 dissociation limit is reported based on modulated ultracold cesium atoms in a dark-spot magneto-optical trap. The atoms are mainly populated in hyperfine level F=3 which is called dark hyperfine state, where atoms are not interacting with trapping light and not influenced by interatomic force. We employed lock-in detection technique by modulating fluorescence of cold atoms to obtain high sensitivity spectroscopy. The signal-to-noise ratio of spectroscopy in dark SPOT is up to 115.6, which is remarkably improved. Our technical proved to be a robust tool for effectively improving the signal-to-noise ratio of atom loss spectroscopy.
