    "abstract": "We have used an ultra-low threshold continuous-wave Optical Parametric\nOscillator (OPO) to reduce the quantum fluctuations of the reflected pump beam\nbelow the shot noise limit. The OPO consisted of a triply resonant cavity\ncontaining a Periodically-Poled Lithium Niobate crystal pumped by a Nd:YAG\nlaser and giving signal and idler wavelengths close to 2.12 microns and a\nthreshold as low as 300 microwatts. We detected the quantum fluctuations of the\npump beam reflected by the OPO using a slightly modified homodyne detection\ntechnique. The measured noise reduction was 30 % (inferred noise reduction at\nthe output of the OPO 38 %).",
