Abstract

We theoretically investigate the enhancement of a selected spectral range in the high-order harmonic generation driven by the multi-color laser fields. The results show that the central wavelength of the enhanced narrow-bandwidth spectrum can be effectively controlled by adjusting the laser intensity and the time delay between laser pulses of different colors, due to the modified electron trajectory in the shaped laser field. Our approach can offer intense, bandwidth controllable single attosecond pulses for attosecond pump-probe experiments.
