Matrix Heater in the Gravitational Wave Observatory GEO 600
Holger Wittel, Christoph Affeldt, Aparna Bisht +7
Large scale laser interferometric gravitational wave detectors (GWDs), such as GEO 600 require high quality optics to reach their design sensitivity. The inevitable surface imperfe…
Alignment sensing and control for squeezed vacuum states of light
Emil Schreiber, Kathrine L. Dooley, Henning Vahlbruch +10
Beam alignment is an important practical aspect of the application of squeezed states of light. Misalignments in the detection of squeezed light result in a reduction of the observ…
Thermal Correction of Astigmatism in the Gravitational Wave Observatory GEO 600
Holger Wittel, Harald Lück, Christoph Affeldt +10
The output port of GEO 600 is dominated by unwanted high order modes (HOMs). The current thermal actuation system, a ring heater behind one of the folding mirrors, causes a signifi…
