摘要：
The recently developed quasi-phase-matching techniques for the high-order harmonics generating in the multiple plasma jets produced on the surfaces of various targets are reviewed. The achievement of 40x enhancement of the quasi-phase-matched harmonics of 804 nm radiation in the range of 35th harmonic in the cases of metal plasmas is analyzed. We demonstrate various approaches in formation of the multi-jet structures during laser ablation by applying the perforated targets and multi-slit shields.
