Abstract


Results on high-order harmonics generation (HHG) by focusing a high power femtosecond laser pulse onto a multi-jet gas puff target with modulated gas density are presented. The use of this target makes possible to increase efficiency of HHG by quasi-phase matching (QPM). Preliminary measurements of high-order harmonics in the extreme ultraviolet range for various experimental parameters are presented. Some improvement of the emission characteristics was observed.
