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…
