C. Martinez et al., SPATIAL CHARACTERIZATION OF THE TRANSVERSAL STRUCTURE OF ROTATIONALLYSYMMETRICAL PULSED BEAMS, Optical and quantum electronics, 29(9), 1997, pp. 923-931
A simple analytical model is proposed to describe the transversal spat
ial 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, b
eam width, quality parameter and kurtosis. As an illustrative experime
ntal example, this model has been applied to high-quality TEA CO2 lase
r pulses.
