Abstract
We report on measurements performed with the Glasgow prototype gravitationa l 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 similar to 5 x 10(-19) m/root Hz which is consist ent 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. (C) 2000 Elsevier Science B.V. All rights reserved.
