要約(英語): A numerical analysis by solving the time-dependent Schrodinger equation on a neon atom within the single-active electron approximation shows that a two-color laser field synthesized from a sub-12-fs fundamental field and a detuned second harmonic field with a wavelength shorter than 380nm is suitable for generating an intense isolated attosecond pulse (IAP). We have also investigated the effects of carrier-envelope phase variation on the obtained IAP and have compared the results to those obtained from a 5-fs fundamental field alone with the same peak field amplitude to show that a more intense IAP can be generated by the two-color laser field which is useful for nonlinear experiments in the extreme ultraviolet spectral range.
