説明
We present the two experimental results of high-order harmonic generation (HHG) using mixed gases target, one is the dramatic enhancement effect, and the other is the destructive and constructive interference of HHG. The dramatic enhancement effect was realized by simultaneous irradiation of XUV attosecond pulse train (APT) to assist optical field ionization. The harmonic yield generated from He atoms increased by a factor of 4×103with booster APT form Xe atoms. And also, the destructive and constructive interference of HHG in a mixed gas of He and Ne facilitate the coherent control of HHG. The observed interference modulation was attributed to the difference between the phases of the intrinsically chirped harmonic pulses from He and Ne, which leads to a novel method for broadband measurement of the harmonic phases. The mixture gas system is an attractive medium not only to control HHG but also to observe ultrafast dynamics of electrons and molecules.
