A Novel Arm-Length Stabilization Scheme for Gravitational-Wave Detectors with AlGaAs/GaAs Coated Mirrors
Jian Liu, Juntao Pan, Carl Blair +7
The arm length stabilisation system is employed in gravitational-wave detectors to reduce the velocity of the mirrors such that the arm cavities can be brought onto resonance in a…

Birefringence in a Silicon Beamsplitter at 2um for Future Gravitational Wave Detectors
Alex Adam, Carl Blair, Chunnong Zhao
The next generation of gravitational wave detectors will move to cryogenic operation in order to reduce thermal noise and thermal distortion. This necessitates a change in mirror s…

Demonstration of optical spring in an un-detuned cavity containing an optical parametric amplifier
Jian Liu, Juntao Pan, Carl Blair +4
Here we demonstrate the capacity to manipulate the optical spring (OS) effect by employing an optical parametric amplifier (OPA) within an optical cavity. We observed more than a f…
