Abstract

We present the experimental observation of pulsed squeezed light from a degenerate optical parametric amplifier pumped by a second harmonic of a continuous-wave mode-locked Nd:YVO4 laser. With a single pass through a 10 mm long periodically poled KTiOPO4 crystal, the classical parametric gain of 11 is observed. The measured noise reduction in the quiet quadrature is 3.2 dB below the shot-noise level.

Schematic diagram of the experimental setup. The second harmonic generated in a bulk PPKTP crystal (PPKTP1) is used to pump the OPA (PPKTP2). The squeezed noise is detected by a homemade balanced homodyne detector. PD1, PD2, photodetectors; PBSs, polarizing beam splitters; LO, local oscillator; ATT, attenuator.

(a) Output probe power versus time with a linear ramp of the probe phase. (b) Classical parametric gain versus pump average power. (c) Estimated parametric gain G ( = exp 2 r ) and effective efficiency η versus the square root of the pump average power.

Fig. 3

(a) Noise power spectrum of homodyne-detected squeezed light where the spectrum-analyzer frequency and the LO phase are swept simultaneously. The shot-noise level and the amplifier noise level versus frequency are also shown. The peak appearing at 75 MHz corresponds to the repetition frequency of the ML laser. (b) The solid curve indicates the noise power for the squeezed light at a fixed radio frequency, 5 MHz, as a function of the LO phase. The dashed curve is a theoretical fit to the data. The amplifier noise is subtracted. The radio-frequency bandwidth is 1 MHz, and the video bandwidth is 10 Hz.
