Abstract
In this work, the laser-parameter effects on the high-order harmonic generation (HHG) spectrum and attosecond trains by mixing two-color laser field, a visible light field of 800nm and a mid-infrared (mid-IR) laser pulses of 2400nm, are theoretically demonstrated for the first time. Different schemes are applied to discuss the function of intensity, carrier-envelope phase (CEP) and pulse duration on the generation of an isolated attosecond pulse. As a consequence, an isolated 16as pulse is obtained by Fourier transforming an ultrabroad XUV continuum of 208eV with the fundamental field of duration of 6fs, 9×1014W/cm2 of intensity, the duration of 12fs, the CEPs of the two driving pulses of −π and the relative strength ratio R=0.2.
