    Concatenation of plasma filaments created in air by femtosecond infrared laser pulses

    We report the first observation of the attachment of two single plasma filaments created collinearly in the atmosphere by IR femtosecond laser pulses. The linked filamentary structure is electrically conductiv...

    Calorimetric detection of THz radiation from femtosecond filaments in air

    Calorimetric measurements of the THz radiation from plasma filaments created in air by intense IR fs laser pulses were performed. The decay kinetics of the THz radiation from this extended plasma source is sho...

    Long-range self-channeling of infrared laser pulses in air: a new propagation regime without ionization

    We report long-range self-channeling in air of multiterawatt femtosecond laser pulses with large negative initial chirps. The peak intensity in the light channels is at least one order of magnitude lower than ...

    Enhanced harmonic conversion efficiency in the self-guided propagation of femtosecond ultraviolet laser pulses in argon

    Harmonic generation during the self-guided propagation of femtosecond ultraviolet (UV) laser pulses (248-nm, 450-fs) in argon is investigated. The third (82.7-nm) and fifth (49.6-nm) harmonics are generated in...

    Femtosecond filament amplification in liquids

    We study the femtosecond filamentation in a liquid amplifying medium, sulphorhodamine 640 in a methanol solvent. In the presence of population inversion, the energy of the filament increases while its diameter...
