Low-vibration cryogenic test facility for next generation of ground-based gravitational-wave observatories Open
We present the design and commissioning of a cryogenic low-vibration test facility that measures displacement noise from a gram-scale silicon cantilever at the level of 10−16m/Hz at 1 kHz. This sensitivity is necessary for future tests of …

Low-vibration cryogenic test facility for next generation of ground-based gravitational-wave observatories Open
We present the design and commissioning of a cryogenic low-vibration test facility that measures displacement noise from a gram-scale silicon cantilever at the level of 10$^{-16}\, \mathrm{m/\sqrt{Hz}}$ at 1kHz. A volume of $\sim$36 litres…

Scattering loss in precision metrology due to mirror roughness Open
Optical losses degrade the sensitivity of laser interferometric instruments. They reduce the number of signal photons and introduce technical noise associated with diffuse light. In quantum-enhanced metrology, they break the entanglement b…

Practical test mass and suspension configuration for a cryogenic kilohertz gravitational wave detector Open
Designs for future gravitational wave detection facilities feature silicon test masses at cryogenic temperatures to reduce thermal noise and thermally induced aberrations. Designers call for operation at 123 K or close to 18 K to exploit t…

Ground Based Gravitational Wave Astronomy in the Asian Region Open
The current gravitational wave detectors have identified a surprising population of heavy stellar mass black holes, and an even larger population of coalescing neutron stars. The first observations have led to many dramatic discoveries and…

Tunable narrow-linewidth laser at 2 μm wavelength for gravitational wave detector research Open
We present and characterize a narrow-linewidth external-cavity diode laser at 2 μ m, and show that it represents a low-cost, high-performance alternative to fiber lasers for research into 2 μ m photonic technologies for next-generation gra…
