    "abstract": "A new scheme for quasi-phasematching high harmonic generation (HHG) in gases\nis proposed. In this, the rapid variation of the axial intensity resulting from\nexcitation of more than one mode of a waveguide is used to achieve quasi\nphasematching. Numerical modeling demonstrates enhancement of the harmonic\nsignal over that achieved for a single coherence length by factors \u003e10^4.",
