Low-amplitude-noise laser for AURIGA detector optical readout
We implemented a laser system to be used in an optical transduction chain for the gravitational-wave bar detector AURIGA ͑Antenna Ultracriogenica Risonante per l'Indagine Gravitazionale Astronomica; Ultracryogenic Resonant Antenna for Astronomical Gravitational Investigation͒. This system is based on a Nd:YAG laser and includes quantum-limited power stabilization in the acoustic range, deep phase modulation and near-quantum-limited rf detection for locking onto optical cavities, and coupling todoi:10.1364/ao.39.005732 pmid:18354570 fatcat:tg5b556ahvcbnnxsnsa7wcqr7y
