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…
Quantitative two-dimensional shadowgraphic set-up for high-sensitivity measurement of low-density laser-plasmas
Amrutha Gopal, Stefano Minardi, Michael Tatarakis
We present a quantitative shadowgraphic method which can measure the density of a laser-generated plasma in air with sensitivity and resolution comparable or better than traditiona…
Shape of the spatial mode function of photons generated in noncollinear spontaneous parametric downconversion
Gabriel Molina-Terriza, Stefano Minardi, Yana Deyanova +3
We show experimentally how noncollinear geometries in spontaneous parametric downconversion induce ellipticity of the shape of the spatial mode function. The degree of ellipticity…
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…
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…
Red solitons: evidence of spatio--temporal instability in spatial-soliton dynamics
Stefano Minardi, Giovanni Blasi, Paolo Di Trapani +4
In three-wave mixing, the noise-seeded spatio--temporal modulational instability has a dramatic impact on the spatial-soliton dynamics, leading to the counterintuitive ob…
