RT Journal Article T1 Spatial characterization of the transversal structure of rotationally symmetric pulsed beams A1 Encinas Sanz, Fernando A1 Serna Galán, Julio A1 Mejías Arias, Pedro Miguel A1 Martínez Herrero, Rosario A1 Martínez, C. AB A simple analytical model is proposed to describe the transversal spatial structure of a tridimensional rotationally symmetric pulsed beam. The spatial behaviour of the pulse amplitude is shown to be linked to its (measurable) second- and higher-order intensity moments, namely, beam width, quality parameter and kurtosis. As an illustrative experimental example, this model has been applied to high-quality TEA CO_2 laser pulses PB Chapman & Hall Ltd.
