A Three-Frequency Heterodyne Detection Laser Communications System for Army Tactical Applications,

Abstract

The carbon dioxide laser represents an excellent transmitter for long range wide bandwidth tactical laser communications systems because of its high efficiency, air-cooled, long lifetime stable operation. In addition, it is well within the state-of-the-art of modulators and detectors to fabricate semi-tactical carbon dioxide laser communications system using conventional techniques. The use of the two frequency approach has been shown to be identical to direct detection but possesses the advantages of the heterodyne configuration and thus offers an interesting alternative to present systems for short paths. The current investigation indicates that the three frequency approach presents an attractive trade-off by allowing a small loss in signal-to-noise margin for a large gain in system simplification.
