Transient Gas-Dynamics Filamentation of High-PowerFemtosecond Laser Pulse in Compressed Argon
Yu. E. Geints, P. V. Babushkin, A. M. Kabanov +2
We have experimentally investigated the spectral characteristics and spatial structure of femtosecond pulses from a titanium:sapphire laser during filamentation in an optical cell…
Energy deposition in air by moderately focused femtosecond laser filaments
Yu. E. Geints, I. Yu. Geints, Ya. V. Grudzin +4
Filamentation of high-power femtosecond laser pulses in air is accompanied by a fairly strong release of optical energy into the propagation medium due to laser-induced ionization…
Photophoretic Movement of a Micron-Sized Light-Absorbing Capsule: Numerical Simulation
Yu. E. Geints, E. K. Panina
Multilayer microparticles with a liquid core and a polycomposite light-absorbing shell (microcapsules) are important components of modern bio- and medical technologies. Opening of…
Toward high-speed effective numerical simulation of multiple filamentation of high-power femtosecond laser radiation in transparent medium
Andrey Bulygin, Yury Geints
High-power femtosecond laser radiation during the propagation in air (and other transparent media) experiences multiple filamentation. Filamentation is a unique nonlinear optical p…
Statistical parameters of femtosecond laser pulse post-filament propagation on 65m air path with localized optical turbulence
Dmitry V. Apeksimov, Andrey V. Bulygin, Yury E. Geints +3
High-power femtosecond laser radiation propagates nonlinearly in air exhibiting pulse self-focusing and strong multiphoton medium ionization, which leads to the spatial fragmentati…
Talbot photolithography optimization with engineered hybrid metal-dielectric mask: High-contrast and highly-uniform Talbot stripes
Yu. E. Geints, I. V. Minin, O. V. Minin
Conventional projection Talbot lithography usually employs opaque (amplitude) or transparent (phase) masks for creating a periodic array of Fresnel diffraction fringes in the photo…
Nonstationary photonic jet from dielectric microsphere
Yu. Geints, E. Panina, A. Zemlyanov
A photonic jet commonly denotes the specific spatially localized region in the near-field forward scattering of a light wave at a dielectric micron-sized particle. We present the d…
