Cheng, G. Zhao, T. Shao, H. Zhu] We present quantum and classical investigation on high order harmonic generation from two-color scheme by employing different infrared (ir) laser parametric source as control pulse with locked carrier envelope phase. We found harmonic continuum bandwidth is in the function of the negative square of the ir-control pulse's wavelength from ir parametric source control field. Moreover, harmonic continuum bandwidth shows a linear dependence on the relative strength ratiok and achieves its extreme value when relative phase shift is around zero. A broad continuum with spectral width of 264eV is observed from a combination field by 6fs, 800nm, 6×1014W/cm2 few-cycle fundamental pulse and half-harmonic control pulse with k=0.5. By further applying a second 10-um ir control pulse, a continuum beyond 353eV is obtained which supports the generation of an isolated 12 attosecond (as) pulse.
