The low frequency interferometer of the Einstein Telescope (ET-LF) requires a prestabilized laser system at a wavelength for which Silicon is transparent. We present a comparison of different laser sources at 1550nm and describe a potential stabilization topology adequate for ET-LF.
B. Willke got his PhD in physics from Leibniz University of Hanover in the field of plasma physics. In 1995 he joined the field of Gravitational Wave (GW) Detection by contributing to the design and installation of the GEO600 GW detector. After a Humboldt fellowship at Stanford University (USA) he returned in 1998 to Hannover to lead the laser effort of the Albert Einstein Institute (AEI). He was in charge of the development, fabrication and installation of the Advanced LIGO prestabilized laser system and his group developed several novel laser stabilization techniques.
