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…

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…

Observing collisions beyond the secular approximation limit

J. Ma, H. Zhang, B. Lavorel +6

Energy transfer through quantum coherences plays an essential role in diverse natural phenomena and technological applications, such as human vision, light-harvesting complexes, qu…
