Quasi-steady-state air plasma channel produced by a femtosecond laser pulse sequence

A long air plasma channel can be formed by filamentation of intense femtosecond laser pulses. However, the lifetime of the plasma channel produced by a single femtosecond laser pulse is too short (only a few nanoseconds) for many potential applications based on the conductivity of the plasma channel. Therefore, prolonging the lifetime of the plasma channel is one of the key challenges in the re...

Extending filamentation

Femtosecond filamentation is an appealing self-organization phenomenon in optical physics that has been awaiting practical applications for a long time. First described some 20 years ago1, the collapse of the spatial beam profile of a femtosecond laser beam may lead to the formation of metre-long plasma channels in atmospheric air. These plasma channels resemble those generated by electric disc...

Direct Measurement of Laser Fluence of Femtosecond Laser Filament in Air

Laser filaments appear spontaneously during the propagation of intense ultrashort laser pulses with a power exceeding a critical value Pcr (Pcr = 5 GW at 800 nm in air) [1]. The intense beam tends to collapse due to the optical Kerr self-focusing effect until the intensity is high enough to ionize the medium, giving rise to a defocusing plasma. Thereafter, a dynamic competition between these tw...

Control of filamentation induced by femtosecond laser pulses propagating in air.

Filamentation formed by self-focusing of intense laser pulses propagating in air is investigated. It is found that the position of filamentation can be controlled continuously by changing the laser power and divergence angle of the laser beam. An analytical model for the process is given.

New THz source in air based on bi-filamentation

A new terahertz source in air based on the bi-filamentation of femtosecond laser pulses is reported. This THz radiation is one order of magnitude more intense than the transition-Cherenkov THz emission from femtosecond laser filaments reported recently and shows different angular and polarization properties. We attribute it to the emission from a bimodal transmission line created by two plasma ...
