Abstract
JPL has a continuing program to environmentally test suitable fiber-based laser transmitters as reliable sources for optical communications from space. In lieu of the availability of fully space qualified systems, commercial pulsed fiber amplifiers either upgraded to meet the necessary environmental requirements or off-the-shelf have been tested under a variety of conditions. Three amplifiers that support high peak powers at 1550 nm have been subjected to vibration, mechanical shock, and thermal cycling tests as well as lifetime vacuum operation. The test results point to the robustness of the commercial technology and the readiness for full space qualification.
