Abstract:   (209 Views)

High-order harmonic generation is a well-established process for producing coherent pulses in the soft-x-ray range by direct frequency conversion of femtosecond near-infrared pulses. Here, we show that a metallic bowtie-shaped gold nanoelement generates the extreme-ultraviolet pulses by means of plasmonic field enhancement. The intensity enhancement factor reaches a peak of ∼8100, allowing generation up to the 85th harmonic of a femtosecond Ti:sapphire laser  in hydrogen gas, with a modest incident intensity of ∼1011 Wcm–2.

Keywords: soft x-ray, plasmonics, femtosecond radiation, high order harmonics.
