Abstract:

A revised propagation model that incorporates the major phenomena important to the propagation of high-power, continuous-wave laser beams has been developed. The code is designed specifically for laser systems analysts who need to know the atmospheres effect on collimated or focused beam propagation. Simplified models are used to calculate the effect of platform jitter, turbulence, and blooming on the beams average intensity and spot area. The blooming model has been revised to incorporate the theoretical and experimental work of Gebhardt and Smith. Some atmospheric parameters e.g., temperature and density are calculated by a standard atmosphere supplied through curve fits of existing theoretical calculations and experimental data. A method of combining this propagation code with the high-energy laser models presented in AFWL-TR-72-154, High-Power Gas Laser Technology Forecast, is described. The combined codes then provide the laser system analysts with a complete evaluation tool. The propagation program listing is given and copies of the card deck are available upon request. Author
