TL;DR: This work demonstrates that these unusual states of neutral atoms can be exploited to create a general ultrafast gain mechanism during laser filamentation, and shows that these states exist in rare gases, at and above atmospheric pressure, where they can act as a gain medium during Laser filamentation.

TL;DR: In this paper, the triggering of single filaments due to turbulence in the beam path for a laser of power below the filamenting threshold was studied, and it was shown that turbulence can act as a switch between the beam not filamenting and producing single filament.

TL;DR: In this paper, the impact of pulse shape on the dynamics of laser-generated plasma in rare gases was investigated and the ability of adequately tailored pulse shapes to optimize the energy deposition in gas plasmas was illustrated.

TL;DR: In this article, the authors present l'application du controle coherent for la discrimination and l'identification des biomolecules dans la phase condensee, based on the modification de phase d'impulsions femtosecondes dans l'ultraviolet profond.

TL;DR: In this paper, the spectral changes in a white light laser filament due to different pulse shapes generated by a pulse shaping setup were examined, and the properties of the filament spectra can be controlled by parametrically tailored white light pulses.
