We carried out experimental and numerical study of the ultrafast supercontinuum generation
by filamentation of 120 fs, 800 nm laser pulses in sapphire under variable focusing …

In this paper, we experimentally investigate supercontinuum generation via collinear two-
color filamentation in sapphire crystal, by launching two femtosecond pulses at fundamental …

The fusion of several coherent 800 nm femtosecond filaments is induced experimentally and
numerically by transmitting a beam through a mask with circular apertures followed by the …

Results of an experimental study of spatial parameters of the region of multiple filamentation
of gigaand terawatt pulses of a Ti: Sapphire laser in glass and water are described. The …

Interaction dynamics of two copropagating femtosecond light filaments in sapphire crystal is
studied by means of time-resolved off-axis digital holographic and shadowgraphic …

Recently, energy exchange between two filaments crossing at small angle and with power
slightly above the critical for self-focusing P cr was experimentally demonstrated. In this …

The results of experiments on the study of spatial characteristics of the multiple filamentation
domain of GW Ti: Sapphire laser pulses in glass are presented. The dependences of the …

Multipass cells (MPCs) recently emerged as a new femtosecond pulse compression
technique for lasers with high pulse energy. While most of the work focused on the …

This paper introduces and discusses the main aspects of multicolored femtosecond pulse
generation using cascaded four-wave mixing (CFWM) in transparent bulk materials …

We study numerically the statistics of the formation of local intensity maxima in the focal
plane of a collecting lens after a Gaussian beam passes through a spiral phase …
