【摘要】 在分析单原子产生高次谐波机制的基础上,给出了扩展谐波平台的新方案。通过采用联合两原子模型代替单原子,在合适的原子核间距,谐波谱的最大截止位置从Ip+3.2Up延展到Ip+8.5Up,且该谐波谱呈现了复杂的多平台结构,并分析了这个复杂结构产生的原因。更多还原

【Abstract】 Based on the analysis of single-atom high order harmonic spectra,A news schemewe is propose to realize the extension of the plateau width.Specifically,by employing a united two-atom model,the harmonic plateau is widened from I_p+3.2U_p in the single-atom case up to I_p+8.5U_p in the united-atom case(at a suitable inter-nuclear separation),and takes on the complex multi-plateau structure.Furthermore,analysis is given on the generation mechanism of these plateaus both qualitatively and quantitatively.更多还原
