Simulations of the filamentation and self-channeling of spatially modulated high-power femtosecond laser pulses in air
Yury Geints, Olga Minina, Alexander Zemlyanov
The propagation of high-power femtosecond laser pulses in air under conditions of superposed spatial phase modulation is considered theoretically. The numerical simulations are car…
Dynamics of femtosecond synthesized coronary profile laser beams filamentation in air
Yu. E. Geints, A. A. Zemlyanov
Multiple filamentation in air of high-power ultrashort laser radiation with transverse intensity profile resembling a "corona" composed by incoherent combining of several annularly…
Overcoming optical contrast limit of mesoscale light focusing by means of retrograde-reflection photonic nanojet
Yury E. Geints, Alexander A. Zemlyanov, Igor V. Minin +1
The physical origin of subwavelength photonic nanojet in retrograde-reflection mode (retro-PNJ) is theoretically considered. This specific type of photonic nanojet emerges upon seq…
