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…
