GEO600, a second generation gravitational wave detector — •Holger Wittel — AEI Hannover

GEO 600 is a ground based gravitational wave detector that is set up as a big Michelson interferometer. Currently, GEO600 is being updated with the goal of increasing the sensitivity by a factor of ten. Central parts of the upgrade are the increase of the circulating light power to above 20kW and the introduction of squeezed light. Both will introduce new challenges: high power operation will make thermal compensation necessary, while squeezing requires a tight loss budget.
