【Abstract】 High-order harmonic generation from He atom in different laser fields has been theoretically investigated by solving the one-dimensional time-dependent Schr dinger equation. The results show that not only can the harmonic spectrum be effectively broaden,but also the quantum path can be controlled with the short quantum path mainly contributing to the high-order harmonics under the interaction of the combined field of monochromatic field,static electric field and the half-cycle laser field.更多还原
