Description

Wavefront radius of Gaussian beam over direction of propagation

English: This diagram shows the relation between the wavefront radius of a Gaussian beam (R) and the direction of propagation (z). The Gaussian beam is a model for laser beams.
Deutsch: Das Diagramm zeigt die Abhängigkeit zwischen dem Radius der Wellenfront R und der Ausbreitungsrichtung z. Der Gaußstrahl ist ein Modell für Laserstrahlen.
