Abstract :
A new approach for high harmonic generation (HHG) with extended cut-off based on the formation of an electron free channel containing dominantly He+ ions is described. A double pulse scheme to control the ionization and phase matching conditions independently by the pulse to pulse separation is employed. X-ray spectra for double pulses excitation for pulse separation is recorded in the range from 0 to 300 fs.
