Temporal characterization of laser pulses using an air-based knife-edge technique
Pierre Béjot, Rishabh Kumar Bhalavi, Adrien Leblanc +4
We present the characterization of ultrashort laser pulses by using the plasma-induced frequency resolved optical switching (PI-FROSt) technique, implemented in ambient air. This r…
Azimuthal modulation instability, breathers and solitons in ring-core optical fibers
Bertrand Kibler, Pierre Béjot
We numerically investigate azimuthal modulation instability in an optical fiber supporting orbital angular momentum modes only, i.e. a vortex fiber, by means of the scalar multimod…
Quadrics for structuring space-time wavepackets
Pierre Béjot, Bertrand Kibler
Space-time light structuring has emerged as a very powerful tool for controlling the propagation dynamics of pulsed beam. The ability to manipulate and generate space-time distribu…
TIGER: TIme-Gated Electric field Reconstruction
F. Billard, R. Sharma, E. Hertz +2
We present a novel self-referenced method for the complete temporal characterization (phase and amplitude) of ultrashort optical laser pulses. The technique, called TIme-Gated Elec…
Multimodal unidirectionnal pulse propagation equation
P. Béjot
In this paper, the unidirectional pulse propagation equation generalized to structured media is derived. A fast modal transform linking the spatio-temporal representation of the fi…
Resonantly enhanced filamentation in gases
J. Doussot, G. Karras, F. Billard +2
In this Letter, a low-loss Kerr-driven optical filament in Krypton gas is experimentally reported in the ultraviolet. The experimental findings are supported by ab initio quantum c…
