A good fraction of the more than 2000 square meter large laboratory space of the AEI is devoted to the experiments in the area of ground based interferometry.
The large floor space and the availability of a crane makes a high bay an ideal location for the AEI 10 m prototype. A second large area is occupied by a copy of the pre-stabilized Advanced LIGO 200 W laser.
Furthermore several experiments are devoted to high power lasers and their stabilization:
The Advanced LIGO laser provides a highly stable 165 W laser beam in a clean spatial mode. This beam is used
- to optimize the power and frequency stabilization of the Advanced LIGO light source [Kwee et al. Opt. Lett. (2011)]
- in a second-harmonic-generation (SHG) experiment to generate a 130 W laser beam at 532nm [Meier et al. Opt. Lett. (2010)]
- to illuminate a diffractive optical element generating a 83W beam in the Laguerre-Gauss LAG33 mode spatially filtered by a ring resonator (in collaboration with University of Birmingham) [Carbone, L. et al. Phys. Rev. Lett. (2013)]
- measure the thermal lens in several optical components as Faraday Isolators, electro-optical modulators and other non-linear optical material that develops under high power illumination (in collaboration with University of Glasgow) [Bogan et al., in prep. (2013)]
