Quasi-steady-state air waveguide
A. Goffin, A. Tartaro, H. M. Milchberg
Abstract
We report a quasi-continuously operating air waveguide, generated by high-repetition-rate patterned filamentation of femtosecond laser pulses. For repetition rates higher than the air thermal relaxation rate, we demonstrate near-continuous guiding of a CW probe beam with significantly improved efficiency.
