Reversibility of laser filamentation.
We investigate the reversibility of laser filamentation, a self-sustained, non-linear propagation regime including dissipation and time-retarded effects. We show that even losses related to ionization marginally affect the possibility of reverse propagating ultrashort pulses back to the initial conditions, although they make it prone to finite-distance blow-up susceptible to prevent backward pr...
متن کاملMultiple filamentation of terawatt laser pulses in air.
The filamentation of femtosecond light pulses in air is numerically and experimentally investigated for beam powers reaching several TW. Beam propagation is shown to be driven by the interplay between intense, robust spikes created by the defects of the input beam and random nucleation of light cells. Evolution of the filament patterns can be qualitatively reproduced by an averaged-in-time (2D+...
متن کاملSherrington-Kirkpatrick spin glass model
In a region above the Almeida-Thouless line, where we are able to control the thermodynamic limit of the Sherrington-Kirkpatrick model and to prove replica symmetry, we show that the fluctuations of the overlaps and of the free energy are Gaussian, on the scale 1/ √ N , for N large. The method we employ is based on the idea, we recently developed, of introducing quadratic coupling between two r...

متن کاملFemtosecond Laser Filamentation in Air
Femtosecond laser filamentation was excited in air. Measurement of the length of the light filament formed was carried out, using calibration method with an analysis on the precision of the measurement. From the photoemission spectra obtained by optic spectrometer, valuable information on the mechanism of interaction of strong laser pulses with atoms and molecules could be obtained. Furthermore...
