Telescope Testing for the LISA Mission
Abstract
The Laser Interferometer Space Antenna (LISA) Mission will listen to the universal sub-Hz gravitational wave concert played by massive black hole mergers, compact galactic binaries and many other expected and unexpected sources. LISA will measure these waves by exchanging laser beams between three spacecraft separated by 2.5Gm. The required 30cm, F#~1 transmit/receive telescopes are part of the interferometer arms. They have to meet several unusual requirements such as pm/√Hz length stability and sub-ppm back scatter of the transmit laser power. We will discuss the telescope test plan and the development and testing of the ground testing equipment.
