154 Plasma HHG Using Femtosecond Pulses
find the conditions when the reduction of harmonic yield becomes
not so dramatic due to some enhancement mechanisms, such as
the presence of in situ produced nanoparticles, which increase the
HHG conversion efficiency. It is worth noting that previous studies of
plasma HHG in carbon plumes [11] have inferred, through analysis
of plasma debris morphology, the formation of nanoparticles during
laser ablation of carbon-contained targets.
Atomic carbon is a reactive species, which stabilizes in various
multi-atomic structures with different molecular configurations ...
