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 pulsesengjournal articlehttp://link.springer.com/article/10.1023%2FA%3A1018533818031?LI=truehttp://link.springer.comopen access535PropagationLightLawsÓptica (Física)2209.19 Óptica Física
