Numerical calculations, near or far field, for the propagation of Gaussian beams via narrow or wide apertures. Input parameters include: wavelength, aperture width, and propagation distance in metric units. Output is provided in graphical and/or numerical form.
Note: the diffraction calculations mentioned here are performed using equations derived from the application of Dirac's notation to propagation in a given geometry. The principles of this approach are described in F. J. Duarte, Tunable Laser Optics (Elsevier-Academic, New York, 2003) (see Chapter 2). Examples of diffractive calculations induced by wide apertures, in the near field, are illustrated in Chapters 2 and 7. This particular near field diffraction distribution corresponds to Fig. 2.11 of Tunable Laser Optics.
