Optical breakdown of air triggered by femtosecond laser filaments

Research output: Contribution to journalArticlepeer-review

40 Scopus citations


We report experiments on the generation of dense plasma channels in ambient air using a dual laser pulse excitation scheme. The dilute plasma produced through the filamentation of an ultraintense femtosecond laser pulse is densified via avalanche ionization driven by a co-propagating multi-Joule nanosecond pulse.
