Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

This paper introduces and discusses the main aspects of ultrashort laser pulse filamentation
in various transparent media such as air (gases), transparent solids and liquids. The …

Transverse electromagnetic waves are important carriers of information and energy. In 1996,
Hellwarth and Nouchi theoretically identified a radically different, non-transverse type of …

Because of their broad spectral width, ultrashort lasers provide unique possibilities to shape
light beams and control their properties, in particular through the use of spatio-temporal …

Introducing angular dispersion into a pulsed field tilts the pulse front with respect to the
phase front. There exists between the angular dispersion and pulse-front tilt a universal …

We present a detailed experimental investigation which uncovers the nature of light bullets
generated from self-focusing in a bulk dielectric medium with Kerr nonlinearity in the …

Abstract de Broglie wave packets accompanying moving particles are dispersive and lack
an intrinsic length scale solely dictated by the particle mass and velocity. Mackinnon …

Can an optical pulse traverse a non-dispersive material at the speed of light in vacuum?
Because traditional approaches for controlling the group velocity of light manipulate either …

The group velocity of 'space-time'wave packets–propagation-invariant pulsed beams
endowed with tight spatio-temporal spectral correlations–can take on arbitrary values in free …

Spatial structuring of an optical pulse can lead in some cases upon free propagation to
changes in its temporal profile. For example, introducing conventional angular dispersion …
