RT Journal Article T1 On the propagation of the kurtosis parameter of general beams A1 Piquero Sanz, Gemma María A1 Mejías Arias, Pedro Miguel A1 Martínez Herrero, Rosario AB The behaviour of the kurtosis parameter of a partially coherent beam that freely propagates is investigated. A general classification scheme of light beams is given in terms of the number of extremals of the kurtosis in free space. Propagation through ABCD optical systems is also considered and a number of general properties of the kurtosis parameter are provided concerning the relationship between the extremals of the kurtosis and the position of the beam waist.
