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