Abstract

Propagation calculations were performed to illustrate the effects of cirrus on high energy laser propagation far field calculations using the 4D wave optics code with adaptive optics (Schafer, 1990). Results show that, for linear effects, subvisible and thin cirrus clouds have small effect on GPL propagation at 1.06 and 3.8 micron. For nonlinear effects for the power/diameter choices, cirrus clouds contribute significant thermal blooming at 3.8 micron for a cirrus thickness above the thin level.
