The influence of circular aperture on the intensity of high-order harmonic generation (HHG) with intense femtosecond las......

Phase-matched high-order harmonic generation in Ar gas-filled cell is investigated experimentally. We obtain phase-match......

Laser pulses with energy of ~10 μJ are generated at 46.9 nm on the 3p-3s transition of the Ne-like Ar by a fast capilla......

电子关联效应在负离子中的作用相当重要，本文讨论了负碳离子（２ｓ＾２２ｐ＾２）和（２ｓ＾１２ｐ＾４）的能级结构、光谱跃迁、寿命和光离解通道等。碳负离子（１ｓ＾２２ｓ＾１ｐ＾４）的双重态比四重......

基于三能级模型,通过数值求解含时薛定谔方程,研究了He原子的极紫外(XUV)光吸收谱.在研究中,利用一束阿秒XUV脉冲将基态的电子激发......
