Status of the GEO 600 squeezed-light laser
Alexander Khalaidovski, Henning Vahlbruch, Nico Lastzka +5
In the course of the high-frequency upgrade of GEO 600, its optical configuration was extended by a squeezed-light laser [1]. Recently, a non-classically enhanced measurement sensi…
Long-term stable squeezed vacuum state of light for gravitational wave detectors
Alexander Khalaidovski, Henning Vahlbruch, Nico Lastzka +4
Currently, the German/British gravitational wave detector GEO600 is being upgraded in course of the GEO-HF program. One part of this upgrade consists of the integration of a squeez…
High-efficiency frequency doubling of continuous-wave laser light
Stefan Ast, Ramon Moghadas Nia, Axel Schönbeck +6
We report on the observation of high efficiency frequency doubling of 1550 nm continuous-wave laser light in a nonlinear cavity containing a periodically poled potassium titanyl ph…
