Paper Abstract

Free space communication systems of today are primarily based on existing microwave and millimeter wave technology. However, recent advances in diode laser technology have provided the impetus for considerable development of free space optical communication systems. A spectral multiplexing beam combiner built for use with diode lasers is described. The design emphasizes a modular approach while minimizing weight and size and demonstrates the technology required for use on free space optical communication satellites. Individual diode laser beams are collimated and aligned before being incoherently combined using narrow bandpass optical filters. The composite output beam is shaped and expanded before leaving the transmitter. Overall wavefront performance, exclusive of sources, was predicted to be 0.05 rms waves at 830 nanometers for the average of the emitted wavefronts.
