Abstract

We report on the performance of a dual-wavelength resonant, traveling-wave optical parametric oscillator to generate squeezed light for application in advanced gravitational-wave interferometers. Shot noise suppression of 8.6 ± 0.8 dB was measured across the detection band of interest to Advanced LIGO, and controlled squeezing measured over 5900 s . Our results also demonstrate that the traveling-wave design has excellent intracavity backscattered light suppression of 47 dB and incident backscattered light suppression of 41 dB , which is a crucial design issue for application in advanced interferometers.
