Reviews: Gaussian beams, Geometrical optics concepts

15 Setembro 2025, 10:00 • José Manuel Rebordão

Gaussian beams: structure of the complex amplitude and interpretation of the different factors. Gaussian distribution of irradiance, divergence. Higher order transverse modes, Hermite and Laguerre.
Geometrical optics: conjugate plane equation and transverse magnification. Some conventions. Plane conjugation. Paraxial approximation. Cardinal points (F, F’. H. H’, N, N’) and origin for measuring distances. Systems with several lenses. Some early warnings about observations in lab.
