Technology development in Hannover for the space-based gravitational wave detector LISA — •Michael Tröbs, Simon Barke, Johanna Bogenstahl, Iouri Bykov, Christian Diekmann, Juan Jose Esteban, Oliver Gerberding, Joachim Kullmann, Maike Lieser, Jens Reiche, Gerhard Heinzel, and Karsten Danzmann — AEI Hannover

Laser Interferometer Space Antenna (LISA) is a future space-based gravitational wave detector consisting of three satellites. LISA shall act as a Michelson interferometer and measure distance variations between free-floating test masses inside the satellites. Currently, the main optical instrument (the optical bench) comprising the interferometers and the electronic device to read out the phase changes (the phasemeter) are being developed.

We give a brief overview on programmatics and report on the progress in Hannover in the optical bench and the phasemeter development.
