Reversibility of laser filamentation.
We investigate the reversibility of laser filamentation, a self-sustained, non-linear propagation regime including dissipation and time-retarded effects. We show that even losses related to ionization marginally affect the possibility of reverse propagating ultrashort pulses back to the initial conditions, although they make it prone to finite-distance blow-up susceptible to prevent backward pr...

متن کاملFemtosecond Laser Filamentation in Air
Femtosecond laser filamentation was excited in air. Measurement of the length of the light filament formed was carried out, using calibration method with an analysis on the precision of the measurement. From the photoemission spectra obtained by optic spectrometer, valuable information on the mechanism of interaction of strong laser pulses with atoms and molecules could be obtained. Furthermore...
متن کاملSome Fundamental Concepts of Femtosecond Laser Filamentation
This paper attempts to clarify some fundamental concepts of femtosecond (fs) laser filamentation in an optical (transparent) medium since there are currently many new applications which are being explored. These range from remote sensing in the atmosphere to few cycle pulse generation, micro-material processing, writing wave guides, fiber Bragg gratings, etc. in the laboratory. For a most recen...
متن کاملFilamentation instability of counterstreaming laser-driven plasmas.
Filamentation due to the growth of a Weibel-type instability was observed in the interaction of a pair of counterstreaming, ablatively driven plasma flows, in a supersonic, collisionless regime relevant to astrophysical collisionless shocks. The flows were created by irradiating a pair of opposing plastic (CH) foils with 1.8 kJ, 2-ns laser pulses on the OMEGA EP Laser System. Ultrafast laser-dr...
