Abstract
We demonstrate nanostructure-enhanced extreme ultraviolet fluorescence from noble gases driven by low-energy, few-cycle light pulses. Despite suffi cient local inten- sities, plasmon-enhanced high harmonic generation is not observed, which follows from the small, nanometer-size coherent source volume.
Highlights
Plasmonic nanostructures with tailored resonances can be utilized to control and enhance optical fields, which allows for the amplification of numerous linear and nonlinear optical processes [1,2,3,4].Here we demonstrate nanostructure-enhanced atomic line emission (ALE) from noble gases driven by short nJ-pulses at high repetition rate
