Abstract
We demonstrate the high-order harmonic generation of femtosecond
pulses in the laser ablation plume containing
the graphene nanoparticles. The harmonics up to the 33rd order were observed.
The presence of graphene
nanoparticles in the laser plasma was confirmed during the analysis of ablation
debris. The comparative studies of
harmonic generation from the ablation of graphene, carbon nanotubes, and diamond
nanoparticles showed the
advanced properties of the latter medium.
