Paper Abstract

The present evaluation of high energy laser beam propagation sensitivity to turbulence effects is based on both analytical results and the far-field calculation results of the Four-Dimensional Wave Optics Code with Adaptive Optics. Attention is given to the way in which turbulence profile intermittencies affect propagation calculation results, as well as the effect of the Kolmogorov inertial subrange model on tilt variance. A statistical analysis was performed on an ensemble of turbulence phase screens, and the results were compared to Sasiela's (1988) theoretical curve. Good agreement is obtained, and the ability to create screens with accurate tilt-variance characteristics appears to be confirmed.
