High-harmonic generation by field enhanced femtosecond pulses in metal-sapphire nanostructure

Abstract Plasmonic high-harmonic generation (HHG) drew attention as a means of producing coherent extreme ultraviolet (EUV) radiation by taking advantage of field enhancement occurring in metallic nanostructures. Here a metal-sapphire nanostructure is devised to provide a solid tip as the HHG emitte... View More
