Measurement of intensity difference squeezing via non-degenerate four-wave mixing process in an atomic vapor

doi:10.1088/1674-1056/22/9/094204

Abstract We report the measurement of the intensity difference squeezing via the non-degenerate four-wave mixing process in a rubidium atomic vapor medium. Two pairs of balanced detection systems are employed to measure the probe and the conjugate beams, respectively. It is convenient to get the quantum shot noise limit, the squeezed and the amplified noise power spectra. We also investigate the influence of the input extra quadrature amplitude noise of the probe beam. The influence of the extra noise can be minimized and the squeezing can be optimized under the proper parameter condition. We measure the-3.7-dB intensity difference squeezing when the probe beam has a 3-dB extra quadrature amplitude noise. This result is slightly smaller than-4.1 dB when the ideal coherent light (no extra noise) for the probe beam is used.

Keywords: four-wave mixing process intensity difference squeezing self-balanced detection
