FIG. 1.

Setup for , filamentation in an argon-filled cylindrical gas cell (length: , inner diameter: ) and charge-coupled device picture of the -long filament channel. : Si photodiodes for measuring energy fluctuations; W: wedges for fine-controlling pulse compression; BS: beam splitter; : diaphrgam. Pulses are characterized in time using SPIDER and high-dynamic-range third-order correlation measurements.

FIG. 2.

Reconstruction of laser pulses at the different stages of the multimillijoule filament. The initial , laser pulse [(a) and (b), dotted line] gets spectrally broadened [(b), bold solid line] and temporally stretched by filamentation [(a), dashed line] due to a large negative GDD of [(b), dashed line]. Compression through bulk material yields a near-transform-limited , pulse [(a), solid line] with an almost flat spectral phase [(b), thin solid line].

FIG. 3.

(a) High dynamic range temporal contrast measurement of the sub- millijoule pulses generated by filamentation. The ASE level is situated around which is close to the detection limit of the apparatus at (dashed line). Prepulses are mainly due to spurious reflections in the third-order correlator apparatus. (b) Wave front measurement of the intense sub- pulses showing residual aberrations of peak to valley and rms.
