Abstract

New time-resolved spatial parameters are given that characterize the behavior of pulsed beams along with their propagation laws through first-order optical systems. The analytical conditions that should be fulfilled so that the intensity-moment formalism remains valid are investigated. Their physical meaning is also discussed, along with the implications for the evolution of the spatial profile of a pulsed beam.
