摘要：

Arising from S. Kim et al. 453, 757—760 (2008); Kim et al. replyPlasmonic nanostructures offer unique possibilities for enhancing linear and nonlinear optical processes. Recently, Kim et al. reported nanostructure-enhanced high harmonic generation (HHG). Here, using nearly identical conditions, we demonstrate extreme-ultraviolet (EUV) emission from gas-exposed nanostructures, but come to entirely different conclusions: instead of HHG, we observe line emission of neutral and ionized gas atoms. We also discuss fundamental physical aspects limiting nanostructure-based HHG. © 2012 Macmillan Publishers Limited.
