Squeezed-state source using radiation-pressure-induced rigidity

摘要: We propose an experiment to extract ponderomotive squeezing from interferometer with high circulating power and low mass mirrors. In this interferometer, optical resonances of the arm cavities are detuned laser frequency, creating a mechanical rigidity that dramatically suppresses displacement noises. After taking into account imperfection elements, noise, other technical noise consistent existing technologies typical laboratory environments, we expect output light have measurable 5 dB, frequency-independent squeeze angle for frequencies below 1 kHz. This source is well suited injection gravitational-wave leading improved sensitivity reduction in quantum noise. Furthermore, design provides experimental test quantum-limited radiation pressure effects, which not previously been tested.
