In the context of optics, a Gaussian beam is a beam of electromagnetic radiation whose transverse electric field and intensity (irradiance) distributions are described by Gaussian functions. Gaussian beams are commonly used in laser science, optical trapping, and nonlinear optics. They are also used in various medical applications such as surgery and diagnostics. In addition, Gaussian beams have been used for beam shaping, where the beam is modified to have a specific spatial distribution, for example, a flat-top profile or a Bessel beam. Overall, the properties and applications of Gaussian beams have been extensively studied and utilized in various fields of science and engineering.
