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 …

Abstract “Non‐diffracting” beams do not spread as they propagate. This property is useful in
many areas. Here, the theory, generation, properties, and applications of various “non …

We generate a broadband “white light” Airy beam and characterize the dependence of the
beam properties on wavelength. Experimental results are presented showing that the …

Space–time (ST) wave packets are coherent pulsed beams that propagate diffraction free
and dispersion free by virtue of tight correlations introduced between their spatial and …

We present the theoretical and experimental study of nondiffracting Bessel beams as a
device for optical manipulation and confinement of nanoparticles. We express analytically …

We report the creation of white-light, achromatic Bessel beams using a spatial light
modulator and a prism to compensate for the dispersion. Unlike the Bessel beam created by …

Of late, generation of different kinds of optical vortex lattices has been gaining much
attention due to various applications. Several methods have been reported for the …

We show that it is feasible to design and manufacture a refractive logarithmic axicon that
generates a quasi-diffraction-free/Bessel beam with nearly constant beam size and intensity …

We report new results related to imaging using broadband Bessel-like beams at the
terahertz (THz) domain that were generated by use of axicons and pulsed THz radiation …
