Filamentation-induced third-harmonic generation in air via plasma-enhanced third-order susceptibility Academic Article

abstract

• We study, both experimentally and theoretically, the underlying physics of third-harmonic generation in air by a filamented infrared femtosecond laser pulse propagating through a thin plasma channel. It is shown that the recently observed more than two-order-of-magnitude increase of the efficiency of third-harmonic generation occurs due to the plasma-enhanced third-order susceptibility. An estimate of the effective value of this susceptibility is given. 2010 The American Physical Society.
