  Fiber lasers entered numerous applications due to their high efficiency and
superior stability. Particularly in space, those lasers have to fulfill
additional requirements set by the harsh environment, typically characterized
by large temperature gradients, vibration and shock as well as different kinds
of radiation. In this contribution, we will report on the development and
realization of a fiber laser intended to operate as part of a Rendezvous and
Docking 3D-Lidar system considering the aforementioned specialties. Power
scaling of pulsed as well as continuous-wave fiber lasers is yet another way to
exploit new application fields in space.
