TL;DR: The GEO 600 laser interferometer with 600 m armlength is currently being commissioned as a part of a worldwide network of gravitational wave detectors as discussed by the authors, and the performance of the detector as of November 2003 is described.

TL;DR: In this paper, a monolithic diode pumped Nd:YAG ring laser was designed and stabilised for the LISA mission, achieving a power stability of δP/P < 2×10−4/Hz and a frequency noise spectral density of <30

TL;DR: In this paper, the GEO 600 laser-diode pumped Nd:YAG laser system is described and the laser frequency stabilization scheme is presented. But, due to the low power noise in the radio frequency region and due to its good spatial beam quality, an injection-locked master-slave design is used for GEO600 laser.
