Abstract
An overview of fiber based components is presented that lead to robust all-fiber lasers and optical amplifiers suitable for space environments. Critical issues impacting the monolithic integration of high power rare earth doped fiber based optical lasers and amplifiers are presented. Optical performance of various all fiber components are reported with emphasis on temperature effects of fiber based pump combiners with polarization maintaining (PM) fiber feed throughs. The all fiber pump combiner is a key component that enables efficient high power pump coupling into double clad rare earth doped optical fibers. A new pump combiner design that injects two fiber coupled pumps plus one PM signal fiber directly into a single polarization maintaining double clad fiber is reported.
