英文摘要	we present a theoretical investigation of high-order harmonic generation in spatially inhomogeneous two-color laser fields by solving three dimensional time dependent schrodinger equation. the cutoff in the harmonic spectra can be significantly extended by means of our proposed method (i.e., from helium interacting with the plasmon-enhanced two-color laser fields), and an ultrabroad supercontinuum up to 1.5 kev is generated by selecting proper carrier-envelope phase of the controlling field. moreover, classical trajectory extraction, time-dependent ionization and recombination rates, and time-frequency analyses are used to explain the generation of this ultrabroadband supercontinuum. as a result, an isolated 8.8 attosecond pulse can be generated directly by the superposition of the supercontinuum harmonics.
