Abstract

The generation of broadband continuous-wave optical squeezing from 280 Hz-100 Hz using a below threshold optical parametric oscillator (OPO) was investigated. The noise locking technique was used to control the squeezed state phase. The low frequency noise sources, speed noise, pump noise and detuning fluctuations were found to have neligible effect on squeezing produced by a below threshold OPO. This low frequency squeezing was found ideal for improving the sensitivity of audio frequency measuring devices like the graviational wave-detectors.
