Extended lifetime of high density plasma filament generated by a dual femtosecond–nanosecond laser pulse in air
A substantially extended lifetime of a high-density plasma channel generated in the wake of an intense femtosecond pulse propagating in air is experimentally demonstrated. Free electron density above 10 ^15 cm ^−3 in the formed plasma filament is measured to be sustained for more than 30 ns. This hi...
