Abstract :
A Ti:sapphire based laser system provided 30-fs pulses centered at 800 nm with up to 3 mJ energy was used in the experiment. The input beam was focused by a concave mirror with radius of 3 m into a 1.5 m long glass cell. No iris-diaphragm or other beam reshaping tools were used for filament adjustment. The gas cell was filled with SF6 or for comparison with Ar at variable pressure of 0.1-0.7 bar. After the filament start point the laser radiation was spatially confined and propagated through the entire gas cell.
