- Abstract:
- Future advanced gravitational-wave detectors, such as Advanced LIGO, Advanced VIRGO, and KAGRA will be limited by noise due to quantum fluctuations in the light, around the most sensitive detection band ~ 100Hz. There are two different approaches for improving the sensitivity: squeezing or canceling the noise by properly designing the input or output optics of the detector, and increasing the response to the gravitational-wave signal by modifying the test mass dynamics. In this project we take advantage of frequency-dependence of the optical spring to effectively reduce inertia of the test mass with multiple optical springs.
