Diode-Laser Transmitter Development for Space-Based Heterodyne Communication
Abstract
An optical transmitter, based on four redundant 30-mW GaA1As diode lasers operating at 0.86 micron, is being developed for an experiment in space- based heterodyne communication. Key optical, mechanical, and electrical components of the transmitter have been fabricated and tested in prototype form. A module which includes the laser, collimator, and electronics has been assembled which yields a wavefront quality of better than labda/30 over a 24 C temperature range. The laser and its four-element collimator have been shaken independently at 49 g (rms) without degradation in performance. The transmitter will weigh less than 2.3 kg and consume less than 4.2 W during normal operation.
