Design and Performance of an On-Satellite Laser Diagnostic System for a Free Space Optical Heterodyne Frequency-Shift-Keyed Communication System.

摘要

The advent of space-based coherent diode laser communication systems requires development of space-qualified laser diagnostics to make these systems robust in face of aging laser parameters. This report describes the packaging and performance of a diagnostic system which sets the wavelength, tone spacing, and optical power of a directly modulated frequency-shift-keyed GaAlAs laser transmitter.
