Abstract:
Concerns the parameterization of the effects of frequency dispersion on
the propagation characteristics of a paraxially approximated pulsed beam (PB)
wavepacket in a lossless medium with generic wavenumber profile. Various
nondimensional measures-critical parameters-have been defined in order to
systematically assess and quantify: a) the effect of dispersion on various
observables associated with the PB field and thereby on the resolution of
these observables; and b) the range of validity of the paraxial approximation
under these conditions.
