70 Watt laser system for ALPS II
The main AEI ALPS II hardware contribution is the 70 Watt high power laser system and components that shape the laser beam to match the Eigenmode of the ALPS II production cavity.
These components are located on an optical table and are referred to as the ALPS II generation system. Many of the mechanical mounts are custom parts built in the AEI's mechanical workshop.
The functional prototype is located in a dust free environment at AEI Hannover and is meant to fit check all components and test some basic operation modes of the ALPS II generation system before it is packed and shipped to the ALPS II site in the HERA north hall at DESY in Hamburg.
