Abstract

Coherent LIDAR systems require a frequency-stable and tunable seed laser source [1]. In general, a cw laser acts as an injection seeder for a Master Oscillator Power Amplifier system. The seed laser has to be a singlefrequency source that can be tuned over several GHz in order to compensate for Doppler-induced frequency shifts of the return signal. For the ESA AEOLUS mission [2], Tesat-Spacecom has developed and flightqualified a cw 1064 nm seed laser, the Reference Laser Head (RLH) for the high-power UV Doppler LIDAR instrument ALADIN [3]. Three RLH flight models (FMs) have been delivered. This paper details their design and performance data measured during development, qualification, and acceptance test campaigns. The lasers and laser diode pump modules are spin-offs of Tesat-Spacecom's development for intersatellite coherent laser communication terminals [4].
