Abstract

The implementation of a mode cleaner at the output port of the GEO 600 gravitational wave detector will be part of the upcoming transition from GEO 600 to GEO-HF. Part of the transition will be the move from a heterodyne readout to a DC readout scheme.DC readout performance will be limited by higher order optical modes and control sidebands present at the output port. For optimum performance of DC readout an output mode cleaner (OMC) will clean the output beam of these contributions.Inclusion of an OMC will introduce new noise sources whose magnitudes needed to be estimated and for which new control systems will be needed.In this article we set requirements on the performance of these control systems and investigate the simulated performance of different designs.
