Imaging the geometrical structure of complex symmetric molecules by above-threshold ionization spectrum in an IR+XUV laser field
Xu-Cong Zhou, Shang Shi, Fei Li +6
Based on the frequency-domain theory, we put forward a method of imaging the complex symmetrical polyatomic molecules by using IR+XUV two-color laser fields. Although the wave func…

Cooper minimum of high-order harmonic spectra from MgO crystal in an ultrashort laser pulse
Yiting Zhao, Xiaoqin Xu, Shicheng Jiang +3
Cooper minimum structure of high-order harmonic spectra from atoms or molecules has been extensively studied. In this paper, we demonstrate that the crystal harmonic spectra from a…

Understanding two-photon double ionization of helium from the perspective of the characteristic time of dynamic transitions
Fei Li, Facheng Jin, Yujun Yang +4
By using the B-spline numerical method, we investigate a two-photon double-ionization (TPDI) process of helium in a high-frequency laser field with its frequency ranging from 1.6~a…
