Gaussian beam intensity equation

WebApr 12, 2024 · There is plenty of intensity outside these diameters. Typically lenses used to focus the beam must have an aperture 1.5 times the beam $\sigma$ based diameter. At that distance from the center, the intensity is about 1% of the central intensity. This is low enough that diffraction effects from truncating the beam are usually negligible. WebThe differential equation to be solved is the Helmholtz equation. A particular solution will be shown to be a Gaussian wave, i.e., a wave whose intensity distribution, transverse to …
