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…

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…

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…

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…

Molecular alignment echoes probe collision-induced rotational-speed changes

J. -M. Hartmann, J. Ma, T. Delahaye +6

We show that the decays with pressure of the alignment echoes induced in N2O-He gas mixtures by two laser pulses with various delays bring detailed information on collision-induced…

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…

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…

Fractional Echoes

G. Karras, E. Hertz, F. Billard +7

We report the observation of fractional echoes in a double-pulse excited nonlinear system. Unlike standard echoes which appear periodically at delays which are integer multiple of…

Dynamics, effciency and energy distribution of nonlinear plasmon-assisted generation of hot carriers

O. Demichel, M. Petit, S. Viarbitskaya +6

We employ nonlinear autocorrelation measurements to investigate plasmon-assisted hot carrier dynamics generated in optical gold antennas. We demonstrate that surface plasmons enabl…

Selective excitation of bright and dark plasmonic resonances of single gold nanorods

O. Demichel, M. Petit, G. Colas des Francs +5

Plasmonic dark modes are pure near-field resonances since their dipole moments are vanishing in far field. These modes are particularly interesting to enhance nonlinear light-matte…
