Performance of the Glasgow 10 m prototype gravitational wave detector operating at λ=1064 nm

We report on measurements performed with the Glasgow prototype gravitational wave detector which has recently been converted to operate with a Nd:YAG laser at 1064 nm. The differential displacement amplitude spectral density above a few hundred Hz is ∼5×10 −19 m/ Hz which is consistent with the limi...

Description
Summary:We report on measurements performed with the Glasgow prototype gravitational wave detector which has recently been converted to operate with a Nd:YAG laser at 1064 nm. The differential displacement amplitude spectral density above a few hundred Hz is ∼5×10 −19 m/ Hz which is consistent with the limitations imposed by shot noise in this frequency range. We also present sensitivity spectra over a lower frequency regime to highlight the impact of improved suspension designs.
