Article: High-power single-frequency Nd:YAG laser for gravitational wave detection
[show abstract] [hide abstract]
ABSTRACT: Experiments on a high-power Nd:YAG rod laser with an output power up to 97 W for the next generation of interferometric gravitational wave detectors will be presented. Furthermore, the highest injection-locked single-frequency output power of 87 W in a linearly polarized, diffraction-limited beam was demonstrated.Classical and Quantum Gravity 02/2004; 21(5):S895. · 3.32 Impact Factor -

Article: Detector description and performance for the first coincidence observations between LIGO and GEO
[show abstract] [hide abstract]
ABSTRACT: For 17 days in August and September 2002, the LIGO and GEO interferometer gravitational wave detectors were operated in coincidence to produce their first data for scientific analysis. Although the detectors were still far from their design sensitivity levels, the data can be used to place better upper limits on the flux of gravitational waves incident on the earth than previous direct measurements. This paper describes the instruments and the data in some detail, as a companion to analysis papers based on the first data.Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, v.517, 154-179 (2004). -
Article: Upper limits on the strength of periodic gravitational waves from PSR J1939+2134
[show abstract] [hide abstract]
ABSTRACT: The first science run of the LIGO and GEO gravitational wave detectors presented the opportunity to test methods of searching for gravitational waves from known pulsars. Here we present new direct upper limits on the strength of waves from the pulsar PSR J1939+2134 using two independent analysis methods, one in the frequency domain using frequentist statistics and one in the time domain using Bayesian inference. Both methods show that the strain amplitude at Earth from this pulsar is less than a few times 10-22.Classical and Quantum Gravity, v.21, S671-S676 (2004).
