Gas-solid phase transition in laser multiple filamentation
Denis Mongin, Elise Schubert, Nicolas Berti +2
While propagating in transparent media, near-infrared multi-terawatt (TW) laser beams break up in a multitude of filaments of typically 100-200 um diameter with peak intensities as…
Conductivity and Discharge Guiding Properties of Mid-IR Laser Filaments
Denis Mongin, Valentina Shumakova, Skirmantas Ališauskas +5
The electric conductivity, HV discharge triggering and guiding capabilities of filaments at 3.9 micrometer in air are investigated in the perspective of lightning control applicati…
Triggering filamentation using turbulence
D. Eeltink, N. Berti, N. Marchiando +5
We study the triggering of single filaments due to turbulence in the beam path for a laser of power below the filamenting threshold. Turbulence can act as a switch between the beam…
Laser filamentation as a new phase transition universality class
Wahb Ettoumi, Jérôme Kasparian, Jean-Pierre Wolf
We show that the onset of laser multiple filamentation can be described as a critical phenomenon that we characterize both experimentally and numerically by measuring a set of seve…
Molecular alignment and filamentation: comparison between weak and strong field models
N. Berti, P. Béjot, J. -P. Wolf +1
The impact of nonadiabatic laser-induced molecular alignment on filamentation is numerically studied. Weak and strong field model of impulsive molecular alignment are compared in t…
Reversibility of laser filamentation
Nicolas Berti, Wahb Ettoumi, Jérôme Kasparian +1
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 r…
High-field quantum calculation reveals time-dependent negative Kerr contribution
Pierre Béjot, Eric Cormier, Edouard Hertz +4
The exact quantum time-dependent optical response of hydrogen under strong field near infrared excitation is investigated and compared to the perturbative model widely used for des…
Transition from plasma- to Kerr-driven laser filamentation
Pierre Béjot, Edouard Hertz, Jérôme Kasparian +3
While filaments are generally interpreted as a dynamic balance between Kerr focusing and plasma defocusing, the role of the higher-order Kerr effect (HOKE) is actively debated as a…
From higher-order Kerr nonlinearities to quantitative modeling of 3rd and 5th harmonic generation in argon
P. Béjot, E. Hertz, B. Lavorel +3
The recent measurement of negative higher-order Kerr effect (HOKE) terms in gases has given rise to a controversial debate, fed by its impact on short laser pulse propagation. By c…
