Abstract Using the Green's function of the scalar wave equation, the program propBG computes and analyzes the far-field amplitude of the harmonics generated when a linearly polarized Gaussian or Bessel–Gauss beam of order zero passes through a dilute gaseous atomic target. The user must supply the relevant atomic data, namely the intensity-dependent atomic dipole moments, linear atomic susceptibilities (both at the fundamental and the harmonic frequencies), and photoionization rate. Target depletion a...
