Paper Abstract

Squeezed state light field can surpass the shot noise limit and improve the signal-to-noise ratio of the sensor measurement. In this paper, based on optical parametric amplification (OPA), we present employed a semi-monolithic cavity and miniaturization design of optical parametric amplifier (OPA) to improve system stability. The infrared spectrum 1064nm quadrature squeezed state field of noise squeezing degree 6.75dB is obtained by pumped the PPKTP crystal via 532nm laser. This work provides a practical light source for quantum sensing detection.
