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…
Three dimensional imaging of short pulses
M. A. C. Potenza, S. Minardi, J. Trull +5
We exploit a slightly noncollinear second-harmonic cross-correlation scheme to map the 3D space-time intensity distribution of an unknown complex-shaped ultrashort optical pulse. W…
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…
A compact, multi-pixel parametric light source
Stefano Minardi, Arunas Varanavicius, Algis Piskarskas +1
The features of a compact, single pass, multi-pixel optical parametric generator are discussed. Several hundreds of independent high spatial-quality tunable ultrashort pulses were…
Spontaneously generated X-shaped light bullets
P. Di Trapani, G. Valiulis, A. Piskarskas +4
We observe the formation of an intense optical wavepacket fully localized in all dimensions, i.e. both longitudinally (in time) and in the transverse plane, with an extension of a…
