WebGaussian 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.
