First Demonstration of Optical Feedback Control to Parametric Instability at Advanced LIGO
Juntao Pan, Carl Blair, Vladimir Bossilkov +5
Increasing the circulating power in gravitational-wave detectors to the megawatt level is essential for future sensitivity improvement, but this is critically limited by optomechan…

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…

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…
