Following the birth of the laser in 1960, the field of" nonlinear optics" rapidly emerged.
Today, laser intensities and pulse durations are readily available, for which the concepts …

Recently, a series of theoretical and experimental papers on free-space propagation of
pulsed Laguerre-Gaussian and Bessel beams was published, which reached contradictory …

By making use of the recently found expression for finite-energy 2D paraxial Airy beam,
three types of ultrashort Airy pulses have been derived and numerically simulated. They …

The diffraction of short pulses is studied on the basis of the Miyamoto-Wolf theory of the
boundary diffraction wave, which is a mathematical formulation of Young's idea about the …

" Thin-film microoptics" stands for novel types of microoptical components and systems
which combine the well-known features of miniaturized optical elements with the specific …

Superluminal propagation of electromagnetic radiation and photon tunnelling have been
studied by a variety of direct and indirect techniques. Especially the use of femtosecond …

We report the generation of aberration-free cylindrical phonon-polariton wave packets in
uniaxial LiTaO 3 crystals by nonresonant impulsive stimulated Raman scattering. The …

We show that the well-known geometric phase, the Gouy phase in optics can be defined for
matter waves in vacuum as well. In particular we show that the underlying physics for the …

It is shown that the focusing of truncated Gaussian beams can be treated by the same
manner as uniform spherical waves, ie, the diffraction integral can be expressed by the …

A simple but exact treatment of spatiotemporal behavior of ultrawideband pulses under an
arbitrarily tight focusing is developed. The model makes use of the oblate spheroidal …
