Abstract : The United Aircraft Research Laboratories are engaged in an experimental and theoretical research program to determine the optimum beam configuration to minimize the deleterious effects of thermal blooming or self-distortion on high power laser beams propagating in the atmosphere. During this initial report period efforts have been largely concentrated on various improvements to the UARL nonlinear propagation code and application of the code to determine the effect of different initial beam shapes on the thermal distortion due to a wind.
