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…
A revisitation of the 1888 H.Hertz experiment
Daniele Faccio, Matteo Clerici, Davide Tambuchi
We propose a revisitation of the original experiment performed by H. Hertz in 1888. With a simple setup it is possible to produce electromagnetic waves with a frequency in the rang…
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…
Far-field spectral characterization of conical emission and filamentation in Kerr media
Daniele Faccio, Paolo Di Trapani, Stefano Minardi +6
By use of an imaging spectrometer we map the far-field () spectra of 200 fs optical pulses that have undergone beam collapse and filamentation in a Kerr medium. By studying th…
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…
