The GEO 600 core optics

[摘要] The optical layout of the interferometric gravitational wave detector GEO600 is described in detail. Criteria for the choice of the geometry of this power- and signal recycled interferometer are presented, including the beam shape inside the interferometer and the surface figure of the optical components. Light power limits for the present setup are discussed. In addition, the demands for the mode cleaners and their performance are given. (C) 2007 Elsevier B.V. All rights reserved.
