SQUEEZING OF THE PUMP BEAM IN OPTICAL PARAMETRIC INTERACTION
Katsuyuki Kasai, Claude Fabre
We investigate the squeezing of the pump beam in optical parametric interaction. According to our semi-classical calculation, the pump beam reflected back from a Triply Resonant Optical Parametric Oscillator (TROPO) is squeezed.1 In this paper we preliminarily demonstrate the squeezing of the pump beam by using a semimonolithic KTP TROPO pumped by a frequency doubled LD-pumped YAG laser. Noise reduction of 1.2 dB below the shot noise level is observed in the bistable region of the parametric oscillation.
