ABCD Gaussian Beam Propagation is an application that calculates the various properties of a laser beam propagating through simple optical elements. It displays the beam and the optical setup in a graphical window that can be manipulated by the user. A table shows the values at all points, they can be copied and used in plotting applications.

Features:
•User-defined inputs (wavelength, radius of curvature, size) and M-square (i.e. multimode equivalence)
•  Calculate propagation through free space, dielectrics, lenses and mirrors. Use toolbars to add elements.
• Calculate eigenmodes of a laser resonator
• Obtain the beam size, radius of curvature, waist size, waist position, and Rayleigh range at any point.
• Copy and paste values (radius, beam size) into your own plotting program
• Copy the physical appearance of the setup as a PDF
• All calculations are performed using the ray matrix formalism (i.e. ABCD matrices) and therefore make the paraxial approximation.
