X and Y waves in the spatiotemporal Kerr dynamics of a self-guided light beam
Miguel A. Porras, Alberto Parola
The nonlinear stage of development of the spatiotemporal instability of the monochromatic Townes beam in a medium with self-focusing nonlinearity and normal dispersion is studied b…
Nonlinear unbalanced Bessel beams in the collapse of Gaussian beams arrested by nonlinear losses
Miguel A. Porras, Alberto Parola
Collapse of a Gaussian beam in self-focusing Kerr media arrested by nonlinear losses may lead to the spontaneous formation of a quasi-stationary nonlinear unbalanced Bessel beam wi…
Collapse-driven spatiotemporal dynamics of filament formation
Miguel A. Porras, Alberto Parola, Daniele Faccio +2
The transition from spatial to spatiotemporal dynamics in Kerr-driven beam collapse is modelled as the instability of the Townes profile. Coupled axial and conical radiation, tempo…
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…
