Higher-order Kerr terms allow ionization-free filamentation in gases
P. Béjot, J. Kasparian, S. Henin +6
We show that higher-order nonlinear indices (, , , ) provide the main defocusing contribution to self-channeling of ultrashort laser pulses in air and Argon…
Arbitrary-order non-linear contribution to self-steepening
J. Kasparian, P. Béjot, J. -P. Wolf
Based on the recently published generalized Miller formula, we derive the spectral dependence of the contribution of arbitrary-order non-linear indices to the group-velocity index.…
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…
Diode laser welding of ABS: Experiments and process modeling
Mariana Ilie, Dominique Grevey, Simone Mattei +2
The laser beam weldability of acrylonitrile/butadiene/styrene (ABS) plates is determined by combining both experimental and theoretical aspects. In modeling the process, an optical…
