Microaxicon-generated photonic nanojets
TL;DR: In this article, optical radiation scattering at micrometer-sized conical-shape dielectric particles (microaxicons) with special attention given to the specific spatially localized near-field area constituting a photonic nanojet (PNJ) was investigated.

Specular-reflection photonic nanojet: physical basis and optical trapping application.
TL;DR: The physical concept of an optical tweezer integrated into the microfluidic device is proposed provided by the calculations of optical trapping forces of the trial gold nanosphere and shows twice as high stability to Brownian motion of the captured nano-bead as compared to the conventional nanojet-based traps.

Peculiarities of filamentation of sharply focused ultrashort laser pulses in air
Yu. E. Geints,Alexander A. Zemlyanov,Andrey A. Ionin,Sergey I. Kudryashov,Leonid V. Seleznev,D. V. Sinitsyn,E. S. Sunchugasheva +6 more
TL;DR: In this paper, the influence of the initial radiation focusing on the main characteristics of laser-induced plasma columns (characteristic transverse size, length, and concentration of free electrons) is considered.

Ring-Gaussian laser pulse filamentation in a self-induced diffraction waveguide
TL;DR: In this paper, the spatial robustness and stability of diffractive waveguides strongly depend on the energy stored in the ring, as well as on its position relative to the beam axis.

Controlling TW-laser pulse long-range filamentation in air by a deformable mirror
D. V. Apeksimov,Yu. E. Geints,A. A. Zemlyanov,Andrey M. Kabanov,V. K. Oshlakov,A. V. Petrov,G. G. Matvienko +6 more
TL;DR: For the first time, to the best of the authors' knowledge, the stable wide-aperture ring-shaped spatial lattice of high-intense light channels is experimentally realized, which can persist over hundreds of meters in air.
