摘要: High-harmonic generation (HHG) provides for efficient and coherent XUV a wide range of spectroscopic applications, enabling attosecond spectroscopy, ultrafast photo-emission or ultrahigh spatial resolution imaging [1]. Conventionally HHG is based on the use high power amplified femtosecond laser pulses, special phase matching techniques, intra-cavity field enhancement. As compelling alternative, resonant plasmonic enhancement in metallic nanostructures has been proposed to achieve necessary peak intensity HHG. Using nJ pulses from Ti:S oscillator, attributed plasmon-enhanced was reported 2008 by group Seung-Woo Kim KAIST Daejeon, Korea, first Ar [2] later
