Triple Michelson Interferometer for a Third-Generation Gravitational Wave Detector
The upcoming European design study ‘Einstein gravitational wave Telescope’ represents the first step towards a substantial, international effort for the design of a third-generation interferometric gravitational wave detector. It is generally believed that third generation instruments cannot be installed into existing infrastructures but will require a new search for optimal detector sites. Con...
متن کاملDual-recycled cavity-enhanced Michelson interferometer for gravitational-wave detection.
The baseline design for an Advanced Laser Interferometer Gravitational-Wave Observatory (Advanced LIGO) is a dual-recycled Michelson interferometer with cavities in each of the Michelson interferometer arms. We describe one possible length-sensing and control scheme for such a dual-recycled, cavity-enhanced Michelson interferometer. We discuss the principles of this scheme and derive the first-...
متن کاملHigh-gain power recycling of a Fabry-Perot Michelson interferometer for a gravitational-wave antenna.
Power recycling was implemented on a fully suspended prototype interferometer with arm lengths of 20 m. A wave-front-sensing technique for alignment control of the suspended mirrors was also implemented, which allowed for several hours of stable operation. A power-recycling gain of greater than 12 was achieved, a significant increase over the highest gain in a suspended mirror Fabry-Perot Miche...
متن کاملExperimental demonstration of a squeezing-enhanced power-recycled michelson interferometer for gravitational wave detection.
Interferometric gravitational wave detectors are expected to be limited by shot noise at some frequencies. We experimentally demonstrate that a power recycled Michelson with squeezed light injected into the dark port can overcome this limit. An improvement in the signal-to-noise ratio of 2.3 dB is measured and locked stably for long periods of time. The configuration, control, and signal readou...
