Abstract
The report describes a mathematical model for solving the propagation problem of laser beams traveling in atmospheric turbulence and corrected by adaptive optics. The modeling of the adaptive optics is mathematically simple but sufficiently general to encompass the majority of the existing systems. The model also includes the effects of beam jitter and partial coherence of the source. The method allows the prediction of the average irradiance and the irradiance variance beam profiles for arbitrary scintillation levels. Typical solutions are presented for 3.8- and 10.6-mu m laser beams. These results illustrate the performance, after propagation in turbulence, of an adaptive system as a function of the wavelength, the number of active elements and the noise level.
