Abstract
We have demonstrated a new technique for detecting ultracold atoms. A balan ced detection technique was used to reduce laser-induced detection noise in conjunction with modulation-transfer spectroscopy to distinguish cold atom s from a thermal cloud. Using this technique, we have achieved signal-to-no ise ratios in excess of 2000:1. (C) 2001 Optical Society of America.
