One approach to detect gravitational waves, which have been postulated by Albert Einstein in his General Theory of Relativity, is based on interferometric measurements of length variations with a large-scale Michelson interferometer. The detection range of these ground-based observatories is currently limited to approx. 15 Megaparsec (Mpc) because of a reduced sensitivity at detection frequencies of 10 Hz ¿ 10 kHz by shot noise. These limitations can be overcome by an output power increase of the detector¿s light source, which will enhance the sensitivity by an order of magnitude. Thus, the ...
