Influence of tunnel ionization to third-harmonic generation of infrared femtosecond laser pulses in air
Here we present an experimental as well as theoretical study of third-harmonic generation in tightly focused femtosecond filaments in air at the wavelength of [Formula: see text] . At low intensities, longitudinal phase matching is dominating in the formation of 3rd harmonics, whereas at higher inte...
