Abstract
We have demonstrated nondestructive detection of cold atoms with a probe la ser by a frequency-modulation spectroscopy technique. We were able to tune the probe laser and its sidebands far from atomic resonance to reduce the s pontaneous emission to less than 0.2 photon per atom during detection.
