Journal ArticleDOI
Power recycling in the Garching 30 m prototype interferometer for gravitational-wave detection
D. Schnier,J. Mizuno,Gerhard Heinzel,Harald Lück,Albrecht Rüdiger,Roland Schilling,M. Schrempel,Walter Winkler,Karsten Danzmann +8 more
TL;DR: In this paper, an experimental realization of power recycling in an interferometer with 30 m arm-length and suspended optical components has been achieved, and the power-recycling factor was about 300, corresponding to a light power of more than 100 W impinging on the beam splitter.
Journal ArticleDOI
Three-port beam splitters-combiners for interferometer applications
TL;DR: It is shown that in the highly undercoupled case almost complete separation of carrier power and phase signal from a cavity strain can be achieved.
Journal ArticleDOI

TL;DR: The double modecleaner system of the British-German interferometric gravitational-wave detector GEO600 as mentioned in this paper uses two high-finesse triangular ring cavities of 8 m optical pathlength each, as an optical mode-cleaning system.
Journal ArticleDOI
Frequency stabilization of a monolithic Nd: YAG ring laser by controlling the power of the laser-diode pump source
TL;DR: An error-point frequency noise smaller than 1mHz/ radicalHz is achieved and a reduction of the power noise of the NPRO by 10 dB without an additional power-stabilization feedback system is reduced.
Journal ArticleDOI
Birefringence-induced losses in interferometers
TL;DR: In this article, the depolarization of the light by inherent or thermally induced birefringence in optical substrates or coatings is determined quantitatively and compared with the losses due to thermal lensing.
