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…
Quantum spatial correlations in high-gain parametric down-conversion measured by means of a CCD camera
O. Jedrkiewicz, E. Brambilla, M. Bache +3
We consider travelling-wave parametric down-conversion in the high-gain regime and present the experimental demonstration of the quantum character of the spatial fluctuations in th…
Detection of sub-shot-noise spatial correlation in high-gain parametric down-conversion
O. Jedrkiewicz, Y. -K. Jiang, E. Brambilla +4
Using a 1GW-1ps pump laser pulse in high gain parametric down-conversion allows us to detect sub-shot-noise spatial quantum correlation with up to one hundred photoelectrons per mo…
Noise-seeded spatio-temporal modulation instability in normal dispersion
D. Salerno, O. Jedrkiewicz, J. Trull +3
In optical second harmonic generation with normal dispersion, the virtually infinite bandwidth of the unbounded, hyperbolic, modulational instability leads to quenching of spatial…
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…
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…
