SC656: Fundamentals of Free-Space Laser Communications

This course introduces the fundamental concepts involved in understanding free-space laser communication system design and performance. Concepts for system and subsystem design using commercially available laser, opto-electronic components, and fast detectors will be developed. Starting from a basic treatment of the effects of atmospheric turbulence and scattering media on high-data-rate laser signals, we discuss how to analyze overall link budget performance including the effects of the atmospheric channel.
