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…

Electromagnetic nonlinear X-waves
C. Conti, S. Trillo, P. Di Trapani +3
Nonlinear optical media that are normally dispersive, support a new type of localized (nondiffractive and nondispersive) wavepackets that are X-shaped in space and time and have sl…
