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 … WebThe Rayleigh length is defined as the distance for which the beam radius is smaller or equal to √2 times the radius at the waist. So, when a focal length is small compared to the incident beam size, the depth of field tends to be small and vice-versa.
