摘要: Coherent EUV light is generated directly from a modest femtosecond laser whose pulse intensity reaches only 1011 W cm− 2. This value in fact two orders of magnitude lower than the threshold required for high harmonic generation using noble gases. The key to this achievement plasmonic field enhancement by means metallic nanostructures fabricated bow-tie shape. method requires no extra cavities amplification and thereby could form basis construct laptop-sized coherent sources many advanced applications lithographic high-resolution imaging.
