Time-resolved refractive index and absorption mapping of light-plasma filaments in water
Stefano Minardi, Amrutha Gopal, Michael Tatarakis +4
By means of a quantitative shadowgraphic method, we performed a space-time characterization of the refractive index variation and transient absorption induced by a light-plasma fil…
Three-dimensional vortex solitons in self-defocusing media
Nikolaos K. Efremidis, Kyriakos Hizanidis, Boris A. Malomed +1
We demonstrate that families of vortex solitons are possible in a bi-dispersive three-dimensional nonlinear Schrodinger equation. These solutions can be considered as extensions of…
Conical emission, pulse splitting and X-wave parametric amplification in nonlinear dynamics of ultrashort light pulses
Daniele Faccio, Miguel A. Porras, Audrius Dubietis +3
The precise observation of the angle-frequency spectrum of light filaments in water reveals a scenario incompatible with current models of conical emission (CE). Its description in…
Non-linear unbalanced Bessel beams: Stationary conical waves supported by nonlinear losses
Miguel A. Porras, Alberto Parola, Daniele Faccio +2
Nonlinear losses accompanying Kerr self-focusing substantially impacts the dynamic balance of diffraction and nonlinearity, permitting the existence of localized and stationary sol…
Non-linear space-time dynamics of ultrashort wave-packets in water
A. Matijosius, J. Trull, P. Di Trapani +4
We have monitored the space-time transformation of 150-fs pulse, undergoing self-focusing and filamentation in water, by means of the nonlinear gating tech- nique. We have observed…
Space-time nonlinear compression and three-dimensional complex trapping in normal dispersion
G. Valiulis, J. Kilius, O. Jedrkiewicz +6
In positive phase-mismatched SHG and normal dispersion, a gaussian spatio-temporal pulse transforms spontaneously into a X-pulse, underlies spatio-temporal compression and eventual…
