Laser Beam Propagation in Turbulent Media

This self-paced advanced training focuses on the propagation behavior of laser beams in turbulent media—an essential subject in the design and analysis of free-space optical (FSO) and quantum communication systems. Through a rigorous yet accessible approach, learners will understand how laser beams are affected by refractive index fluctuations in both atmospheric and underwater environments.
