Space laser components reliability

Kurzfassung

Space environment presents unique challenges for operation of optics and optical coatings as part of laser systems. Besides testing components and sub-systems on the component qualification level, the extended testing of complete laser systems like flight modules under acceptance level conditions is an effective way to determine the reliability and long term stability, mitigating the mission risk. Hence, optics as part of high power space laser systems have to be extensively tested in view of an upcoming mission. The goal is to identify and mitigate production flaws, and to optimize the laser environment, such that a safe operational margin can be maintained over the expected lifetime in orbit.
