摘要: We report on the experimental combination of three advanced interferometer techniques for gravitational wave detection, namely, power recycling, detuned signal and squeezed field injection. For first time, we experimentally prove compatibility especially latter two. To achieve a broadband nonclassical sensitivity improvement, applied filter cavity compensation quadrature rotation. The signal-to-noise ratio was improved by up to 2.8 dB beyond coherent state's shot noise. complete setup stably locked arbitrary times characterized injected single-sideband modulation fields.
