This excess noise precludes the use of these fiber lasers in a range of precision interferometry and quantum optics applications. We present experimental results using a passive, high Q, fiber ring resonator to filter out up to 26 dB of excess laser intensity noise, resulting in a stabilized laser output that reaches the shot-noise limit over most of its signal spectrum.Keywords: Laser noise suppression; Passive fiber resonator; Passive fiber ring cavity; Optical resonators; Quantum optics; Shot noise; Fiber lasers Laser noise suppression; Passive fiber resonator; Passive fiber ring cavity (FRC)200710.1109/LPT.2007.8994662015-12-08
