Abstract:
Plasma high harmonics generation from an extremely intense short-pulse laser
is explored by including the effects of ion motion, electron-ion collisions and
radiation reaction force in the plasma dynamics. The laser radiation pressure
induces plasma ion motion through the hole-boring effect resulting into the
frequency shifting and widening of the harmonic spectra. Classical radiation
reaction force slightly mitigates the frequency broadening caused by the ion
motion. Based on the results and physical considerations, parameter maps
highlighting optimum regions for generating a single intense attosecond pulse
and coherent XUV radiations are presented.
