Abstract

We describe recent results explaining the behavior of optical turbulence effects on the propagation of initially convergent (focused) laser beams. First we discuss the diffractive characteristics of an initially convergent Gaussian beam based on the geometric properties of the diffractive beam parameters. Some behaviors previously attributed to optical turbulence effects can instead be explained by the diffractive nature of the beam itself. We give expressions for the location and size of the beam waist, maximum possible distance from the transmitter to the beam waist, and the optical radius of curvature for focusing in turbulence. Laser, we present turbulent beam parameters consistent with our previously defined diffractive beam parameters.
