Qualification Testing of a Diode-Laser Transmitter for Free-Space Coherent Communications

Abstract

A diode-laser transmitter designed for space-based coherent communications has been successfully space qualified. Environmental testing, which consisted of random vibration at levels up to 16.2 g rms and thermal cycling over the range of -30 to 66 C, caused no significant degradation in the performance of the transmitter. Principal design issues and the qualification process of subassemblies and the complete transmitter are described.
