Spatiotemporal helicon wavepackets
Pierre Béjot, Bertrand Kibler
Propagation-invariant or non-diffracting optical beams have received considerable attention during the last two decades. However, the pulsed nature of light waves and the structure…
Quantized conical waves in multimode optical fibers
Bertrand Kibler, Pierre Béjot
Multimode optical fibers has emerged as the platform that will bridge the gap between nonlinear optics in bulk media and in single-mode fibers. However, the understanding of the tr…
Doppler effect as a tool for ultrashort electric field reconstruction
P. Béjot, E. Szmygel, A. Dubrouil +4
Technological advances in femtosecond laser sources call for the development of increasingly refined characterization tools implying to enrich the existing panel of operable nonlin…
Optical imaging of coherent molecular rotors
Jérémy Bert, Emilien Prost, Ilia Tutunnikov +7
Short laser pulses are widely used for controlling molecular rotational degrees of freedom and inducing molecular alignment, orientation, unidirectional rotation and other types of…
Ab-initio calculations of laser-atom interactions reveal harmonics feedback during macroscopic propagation
Nicolas Berti, Pierre Béjot, Eric Cormier +3
We couple the full 3D ab initio quantum evolution of the light pulse polarization in interaction with an atom with a propagation model to simulate the propagation of ultrashort las…
Energy conservation in self-phase modulation
Pierre Béjot, Jérôme Kasparian
Spectral broadening of ultrashort laser pulses is simultaneously described by either self-phase modulation (SPM) or four-wave mixing (FWM). The latter implies the instantaneous con…
