High power optical amplifier at 1.5 µm for GEO and LEO optical feeder links

In the frame of the FOLC2 project, in cooperation with Airbus Defence and Space, CILAS developed, manufactured and qualified an in-orbit demonstrator model (IODM) of a 5-W space-grade high power optical amplifier (HPOA), at 1.5 μm, for both LEO and GEO laser communication terminal feeder links. It is designed to amplify single-channel or multi-channel signal, from 1555 to 1565 nm, up to 5 W with limited noise, limited gain flatness and very good efficiency, with its own space-grade electronics. The IODM HPOA will be embedded in the GEO optical terminal demonstrator TELEO, developed by Airbus Defence and Space
