Abstract
Theoretical investigation of high-order harmonic generation by metallic carbon nanotubes exposed to an intense ultrashort pulse was done in the semiclassical approximation. The results showed efficient generation of high-order harmonics with intensities falling down with harmonic number, due to the high density of conduction electrons in metallic carbon nanotubes and the specific dispersion law inherent in hexagonal crystalline structure. Phase matching for different harmonics in parallel-alligned carbon nanotubes was also studied.
