Diffraction-free and dispersion-free pulsed beam propagation in dispersive media.

The diffraction of pulsed beams of light is formulated as an anomalously dispersive phenomenon. In a dispersive material, the effects of material group-velocity dispersion and diffraction on pulsed beam propagation can mutually cancel if the transverse profile of the pulse is suitably chosen.

Pulsed-beam propagation in lossless dispersive media. I. Theory

This first part of a two-part investigation is concerned with the effects of dispersion on the propagation characteristics of the scalar field associated with a highly localized pulsed-beam (PB) wave packet in a lossless homogeneous medium described by the generic wave-number profile k(v) 5 v/c(v), where c(v) is the frequency-dependent wave propagation speed. While comprehensive studies have be...

Free-Space Ultrashort Pulsed Beam Propagation Beyond the Paraxial Approximation

Applying the temporal and spatial Fourier transform method, we obtain a nonparaxial pulsed beam solution, which is based on the paraxial pulsed beam solution, where the nonparaxiality is evaluated by using a series of expansions. Specifically, the general lowest-order correction field is given in an integral form. Some special examples, such as the lowest-order correction to the paraxial approx...

Far-field diffraction of pulsed optical beams in dispersive media

Ž . Propagation of a pulsed optical beam a train of ultrashort optical pulses inside a linear dispersive medium is studied in the far field without making the paraxial approximation. This approach permits us to obtain analytical results that are valid for relatively large diffraction angles. Pulse characteristics are found to be affected considerably by the combination of diffraction and disper...

Asymptotic description of pulsed ultrawideband electromagnetic beam field propagation in dispersive, attenuative media.

The asymptotic description of the coupled spatial and temporal evolution of a pulsed ultrawideband electromagnetic beam field as it propagates through a dispersive, attenuative material that occupies the half-space z > or = z(0) is obtained from the angular spectrum of plane waves representation. This angular-spectrum representation expresses the wave field as a superposition of both homogeneou...
