Abstract
Tuning of the harmonic wavelength by varying the driving radiation wavelength, chirp, and intensity during the interaction of Ti:sapphire laser radiation with preformed laser plasma and solid surfaces was studied. High-order harmonics (HHG) were studied at different spectral, phase, and intensity characteristics of femtosecond radiation. Analysis of the variation of the high-order harmonic distribution in the case of different plumes is presented. We show that the tuning of harmonic wavelength allows achievement of resonance enhancement of single harmonics in the plateau distribution of HHG.
