Non-linear Synthesis of Complex Laser Waveforms at Remote Distances
Nicolas Berti, Wahb Ettoumi, Sylvain Hermelin +2
Strong deformation of ultrashort laser pulse shapes is unavoidable when delivering high intensities at remote distances due to non-linear effects taking place while propagating. Re…
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…
Generalized Miller Formulae
W. Ettoumi, Y. Petit, J. Kasparian +1
We derive the spectral dependence of the non-linear susceptibility of any order, generalizing the common form of Sellmeier equations. This dependence is fully defined by the knowle…
Spectral dependence of purely-Kerr driven filamentation in air and argon
W. Ettoumi, P. Béjot, Y. Petit +6
Based on numerical simulations, we show that higher-order nonlinear indices (up to and , respectively) of air and argon have a dominant contribution to both focusing…
