We demonstrate that femtosecond filaments can set up an extended and robust thermal
waveguide structure in air with a lifetime of several milliseconds, making possible the very …

Nonlinear optical methods have become ubiquitous in many scientific areas, from
fundamental studies of time-resolved electron dynamics to microscopy and spectroscopy …

Results of experimental and theoretical investigations of the hybrid (solid state/gas) visible-
range femtosecond systems THL-100 (IHCE SB RAS) and THL-30 (PN Lebedev Physics …

Nonlinear pulse compression techniques have been applied widely in the pursuit of ultra‐
intense laser pulse with extremely high pulse energy (≈ mJ) and extremely short pulse …

Vortex beams with orthogonality can be widely used in atmospheric applications. We
numerically analyzed the statistical regularities of vortex beams propagating through a lens …

Broadband laser sources based on supercontinuum generation in femtosecond laser
filamentation have enabled applications from stand-off sensing and spectroscopy to the …

Exploring the influence of atmospheric turbulence on remote sensing based on filament-
induced fluorescence is still challenging. In this study, we applied artificial turbulence during …

Formation of light bullets—tightly localized in space and time light packets, retaining their
spatiotemporal shape during propagation—is, for the first time, experimentally observed and …

We propose a feedback-based wavefront sha** with an annular phase mask to control the
spatial characteristics of femtosecond laser filamentation in K9 glass. A closed-loop …

The propagation of the Pearcey pulse with a linear chirp is investigated in detail. We find that
the chirp parameter has an impact on the focusing property of the Pearcey pulse. We further …
