摘要: We have proposed a metallic dipole-ellipsoid-bagel nanostructure, which could effectively control the enhanced plasmonic fields within two-color laser for producing isolated attosecond pulses. This nanostructure enables multiple resonances leading to broad overall bandwidth, benefits high harmonic generation (HHG) and production of pulses via field. The enhance field intensity exceed 103 in volume 10 × 5 nm3. pulse with duration 155 as is obtained 15-fs incidence. would benefit application ultra-sensitive multi-color sensor generation.
