摘要

High-order harmonic and attosecond pulse generation driven by a synthesized laser field with two laser pulses of controlled related phase is reviewed. High-order harmonic generation (HHG) is a strongly nonlinear response of a medium to the driving laser field. By controlling the laser field on subcycle timescale carefully, the motion of the electron can be accurately steered to generate the isolated attosecond pulse, to enhance the conversion efficiency of HHG, to adjust the phase of the harmonic emission spectra and so on.
