Abstract

The stability and nonlinear evolution of a long, low-intensity laser filament (τ_L=400ps, I∼10^10-12 Wcm^-2) propagating in an underdense plasma (n_e=10¹⁹∼10 ²⁰ cm^-3) are studied. A 2-D time-resolved sampling diagnostic monitors the beam dynamics. It is found that the filament is not stable as a function of time even for beam power that is few orders of magnitude below the ponderomotive self-focusing threshold. Such instabilities can be reduced by propagating another laser pulse, at similar pulse energy, ahead of the laser pulse.
