Abstract
Laser beam propagation through atmospheric turbulence may result in strong intensity fluctuations at the receiver plane of a free-space communication link. To minimize intensity fluctuations, we consider an approach based on the use of a dynamic random phase diffuser placed in the transmitter plane. To create a phase diffuser having controlled statistical properties, a nonlinear optical system with 2D feedback (artificial optical turbulence generator) is used. This system can provide real-time laser beam spatial coherence control for a laser transmitter in order to optimize laser communication link performance.
