Abstract

Directed energy (DE) systems composed of large numbers of combined laser beams have been proposed for a number of applications, including illumination of photovoltaic cells on the moon and spacecraft propulsion. It is important to understand how the design parameters of these systems and perturbations such as misalignment and phase error affect their performance. It is also useful to evaluate the effects of phase and amplitude screens. This paper describes the development of a tool that can simulate the beam profile of over ten billion coherently combined laser elements at astronomical distances with user set locations, mode fields, amplitudes, phases, and pointing vectors.
