Abstract
In atmospheric optics it has become common practice to model the energy input or outer scale using a von Karman model. In terms of the turbulence power spectral density this model assumes that the slope of contributions outside the inertial range are uniform from the outer scale to zero spatial frequency. Recently, it has been suggested that energy outside in the buoyancy range may instead have a slope of -15/3 or -17/5 compared to a 3D index of refraction model in the inertial range of -11/3. The possible existence of these ranges has been suggested as one source for observations of non-Kolmogorov turbulence. In this work, I use wave optics simulation to evaluate the effect of these varied models on the beam wander of a collimated Gaussian beam and compare the results to the von Karman model.
