Abstract

Stable squeezed noise sources of large magnitude across the audio frequency band has generated great interest in the gravitational wave community as a means for improving the quantum-noise-limited performance of advanced interferometric detectors. We present our most recent results showing 8.5dB of squeezing over most of the frequency band of interest for ground based detectors. We discuss many of the issues that were overcome in order to reach this level of squeezing at these frequencies such as scattered light, beam jitter and electronics.
