摘要: We report a drastic reduction of air resistivity following the passage self-guided femtosecond pulse from Ti:sapphire laser system at 800 nm with energies per between 1 and 14 mJ duration 120 fs. Connected plasma filaments length that can exceed 150 cm are created by these pulses. The presence conducting channel results multiphoton ionization molecules in filament core.
