Laser pulse propagation in a meter scale rubidium vapor/plasma cell in AWAKE experiment
Atefeh Joulaei, Joshua Moody, Nicolas Berti +3
We present the results of numerical studies of laser pulse propagating in a 3.5 cm Rb vapor cell in the linear dispersion regime by using a 1D model and a 2D code that has been mod…
Non-linear photochemical pathways in laser induced atmospheric aerosol formation
Denis Mongin, Jay G. Slowik, Elise Schubert +7
We measured the chemical composition and the size distribution of aerosols generated by femtosecond-Terawatt laser pulses in the atmosphere using an aerosol mass spectrometer (AMS)…
Remote electrical arc suppression by laser filamentation
Elise Schubert, Denis Mongin, Jérôme Kasparian +1
We investigate the interaction of narrow plasma channels formed in the filamentation of ultrashort laser pulses, with a DC high voltage. The laser filaments prevent electrical arcs…
Non-linear Synthesis of Complex Laser Waveforms at Remote Distances
Nicolas Berti, Wahb Ettoumi, Sylvain Hermelin +2
Strong deformation of ultrashort laser pulse shapes is unavoidable when delivering high intensities at remote distances due to non-linear effects taking place while propagating. Re…
Spin-Glass Model Governs Laser Multiple Filamentation
Wahb Ettoumi, Jérôme Kasparian, Jean-Pierre Wolf
We show that multiple filamentation patterns in high-power laser beams, can be described by means of two statistical physics concepts, namely self-similarity of the patterns over t…
