38 Theoretical Basics of Plasma Harmonics
cycle, which requires the appropriate experimental technique (i.e.,
such focusing that the collective effects due to the macroscopic
propagation select only one peak). Taking into account a smooth
dependence of the harmonic intensity on the laser intensity, and
that it is not necessary to manipulate with long and short orbits by
appropriate focusing, one can expect that resonant HHG has a bright
perspective for applications in attoscience [61, 62].
The HHG in the presence of a shape resonance was analyzed
in [56]. To understand the HHG mechanism, ...
