The high-order harmonic generation from boron plasma was studied using the
longitudinal pump scheme. The harmonics up to the 57th order (
nm) were observed. The characteristics of plateau in the range of 15th
to 57th harmonics were analyzed depending on fundamental radiation
intensity and the saturation of harmonic cutoff was observed. The harmonic
cutoff energy was restricted by the self-defocusing of femtosecond
radiation. A comparison of longitudinal and orthogonal pump schemes of boron
plasma excitation was presented.
