Nature of problem:
The program calculates conversion efficiencies and spatio-temporal far-field profiles of harmonics generated by a gaseous target irradiated by an intense Gaussian or Bessel-Gauss beam, given the relevant atomic data.
The harmonic far-field amplitude is expressed as an integral over the medium, with the help of the retarded Green's function of the propagation equation, and is evaluated by numerical quadrature.
The optional use of the routine S17DEF of the NAG Fortran Library .
Depends crucially on the complexity of the problem. About 18 minutes for the test data on a SGI Origin 2000 machine (R10000 processor running at 195 MHz).
