Plasmon-assisted high harmonic generation in vicinity of metal nanostructures
Max Born Institute , Germany
We develop a theory of high harmonic generation enabled by plasmonic field enhancement in a vicinity of metal nanoparticles. The theory accounts for the changes in the harmonic spectrum due to the field inhomogeneity and collisions of electrons with the metallic surface. The possibilities to use this technique for generation of single attosecond pulses, high harmonic generation in the vicinity of random surfaces, as well as high harmonic generation in gas-nanoparticle mixtures are also studied.
