Enhanced harmonic generation in C60-containing plasma plumes

The results of enhanced harmonic generation in fullerene-containing plasma plumes using laser radiation of different wavelengths, pulse durations, and phase modulation are presented. Odd and even harmonics up to the 29(th) order of 800 nm radiation have been extended in the case of two-color orthogonal polarization pump of C-60-containing plasma plumes. The conversion efficiency for the odd and even harmonics in the vicinity of SPR of the C-60-containing plasma (40-70 nm) was estimated to be in the range of 10(-4).
