摘要：

Generation of the second and third harmonics of 80-fs 1-mJ pulses from a Ti:sapphire laser in the plasma of self-induced optical breakdown in atmospheric air is studied. Spatial self-action of fundamental radiation accompanied by the broadening of spectra of fundamental radiation and optical harmonics is revealed. The self-action of light leads to the saturation of the efficiency of third-harmonic generation as a function of the energy of fundamental radiation. An efficiency of third-harmonic generation up to 1.7x10(-3) is achieved with 1-kHz laser pulses.
