SSPARAMA: A Nonlinear, Wave Optics Multipulse (and CW) Steady-State Propagation Code with Adaptive Coordinates

Abstract

This report describes the numerical procedures that are used to calculate the steady-state atmospheric propagation and thermal blooming of either a train of high-energy laser pulses or a CW beam. The calculation is performed through the aid of a sequence of coordinate and variable transformations that enable one to adapt the scale and location of the transverse coordinate system to the amount of diffraction or thermal blooming taking place during beam propagation. A description is also given of the input parameters and diagnostics provided in the calculation along with a listing of the computer program. (Author)
