Lidaris and ESA start a new project ESPRESSO

Laser systems operating in space require well-characterized optics, which are able to ensure long-term failure-free operation and perform effectively under high average output power. If an optical element used in the laser system would become damaged, the performance of the laser can be seriously reduced or even destroyed. Furthermore, a damaged optical element would also endanger the entire space project since there is almost no possibility to repair optic’s degradation in the orbit.

Up to now, the ability to predict optic’s longevity required by space programs is limited by insufficient experimental data and lack of the validated prediction models. In order to solve this problem, Lidaris and ESA join forces for a two years collaboration project ESPRESSO. The overall aim of the project is to carry out research and development work required for essential preparation of reliable longevity qualification procedure to evaluate high power laser optics with intended use in space applications.
