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.
