    From the lesson. Geometrical Optics for Gaussian Beams. First order optical system design using rays is useful for the initial design of an optical imaging system, but does not predict the energy and resolution of the system. This module introduces Gaussian beams, a specific example of how the shape of the light evolves in an imaging system.

Gaussian beam - Wikipedia

    https://en.wikipedia.org/wiki/Gaussian_beam
    For a Gaussian beam, the BPP is the product of the beam's divergence and waist size w 0. The BPP of a real beam is obtained by measuring the beam's minimum diameter and far-field divergence, and taking their product. The ratio of the BPP of the real beam to that of an ideal Gaussian beam at the same wavelength is known as M 2 ("M squared").

Gaussian beam-shaping using ray-tracing approach

    https://spie.org/Publications/Proceedings/Paper/10.1117/12.519806
    Ray tracing is one of the methods to design diffractive optical elements. We included this theory to obtain two or four Gaussian beans from one Gaussian beam. The power distribution has been calculated by near field diffraction. First we considered one dimensional case and then the two dimensional case.

Gaussian Beam Optics - Newport

    Gaussian Beam Optics. The Gaussian is a radially symmetrical distribution whose electric field variation is given by the following equation: r is defined as the distance from the center of the beam, and ω 0 is the radius at which the amplitude is 1/e of its value on the axis. The Fourier Transform of this equation is also a Gaussian distribution.

Gaussian Beamlet Propagation — Raypier 0.1 documentation

    https://raypier-optics.readthedocs.io/en/latest/gaussian_beamlet_propagation.html
    Gaussian beams are a solution to the paraxial wave equation. It turns out that the propagation of such modes can be represented by a chief ray and a number of skew marginal rays which define the 1/e^2 edge (and divergence) of the beam. ... This method provides a convenient route to extend a geometric ray-tracing algorithm to obtain a physical ...

Gaussian beam tracing for computing ocean acoustic fields

    https://asa.scitation.org/doi/abs/10.1121/1.395269
    The method of Gaussian beam tracing has recently received a great deal of attention in the seismological community. In comparison to standard ray tracing, the method has the advantage of being free of certain ray‐tracing artifacts such as perfect shadows and infinitely high energy at caustics. It also obviates the need for eigenray computations.
