Experimental observation of spontaneous emission of space-time wavepacket in a multimode optical fiber
Karolina Stefańska, Pierre Béjot, Karol Tarnowski +1
We provide a complete analysis, from theory to experiment, of the spontaneous emergence of a discretized conical wave of X-type (i.e., a localized 2D+1 space-time wavepacket) when…
Visualizing coherent molecular rotation in a gaseous medium
Ilia Tutunnikov, Emilien Prost, Uri Steinitz +5
Inducing and controlling the ultrafast molecular rotational dynamics using shaped laser fields is essential in numerous applications. Several approaches exist that allow following…
Molecular alignment and filamentation: comparison between weak and strong field models
N. Berti, P. Béjot, J. -P. Wolf +1
The impact of nonadiabatic laser-induced molecular alignment on filamentation is numerically studied. Weak and strong field model of impulsive molecular alignment are compared in t…
High-field quantum calculation reveals time-dependent negative Kerr contribution
Pierre Béjot, Eric Cormier, Edouard Hertz +4
The exact quantum time-dependent optical response of hydrogen under strong field near infrared excitation is investigated and compared to the perturbative model widely used for des…
Conical emission from laser filaments and higher-order Kerr effect in air
Pierre Béjot, Jérôme Kasparian
We numerically investigate the conical emission (CE) from ultrashort laser filaments, both considering and disregarding the higher-order Kerr effect (HOKE). While the consideration…
Transition from plasma- to Kerr-driven laser filamentation
Pierre Béjot, Edouard Hertz, Jérôme Kasparian +3
While filaments are generally interpreted as a dynamic balance between Kerr focusing and plasma defocusing, the role of the higher-order Kerr effect (HOKE) is actively debated as a…
