A comparative review is given of some well-known and some recent results obtained in
studies of two-and three-dimensional (2D and 3D) solitons, with emphasis on states carrying …

Ultrafast laser materials processing has undergone an important change with the
development of non-diffracting beams. These beams enable overcoming many of the …

Modern laser sources nowadays deliver ultrashort light pulses reaching few cycles in
duration and peak powers exceeding several terawatt (TW). When such pulses propagate …

Optical collapse is a fascinating research topic. The propagation of intense laser beams in a
transparent medium is usually modeled by the two-dimensional nonlinear Schrödinger …

The first-order helical Laguerre–Gaussian mode (also called donut mode) is used to
improve the energy throughput of nonlinear spectral broadening in gas-filled multipass cells …

The pulse duration at the output of femtosecond lasers is usually close to the Fourier limit,
and can be shortened by increasing the spectral width. To this end, use is made of self …

The distant projection of high-peak and average-power laser beams in the atmosphere is a
long-standing goal with a wide range of applications. Our early proof-of-principle …

High-order harmonic generation (HHG) has been recently proven to produce extreme-
ultraviolet (XUV) vortices from the nonlinear conversion of infrared twisted beams. Previous …

The irradiances or fluences encountered in pulsed fiber lasers and amplifiers are sometimes
high enough to destroy the fiber. The ultimate limit is set by the intrinsic damage threshold …

We investigate the self-focusing dynamics of super-Gaussian optical beams in a Kerr
medium. We find that up to several times the critical power for self-focusing, super-Gaussian …
