二氧化碳分子内壳层轨道对阿秒脉冲整形的影响
Influence of inner orbitals of CO2 molecules on attosecond pulse shaping
摘要
Abstract
Based on the quantitative rescattering model and the theory of propagation of high harmonics in a macroscopic medium,the physical mechanism of the influence of the inner orbitals of CO2 molecules on attosecond pulse shaping was revealed.By comparing high-order harmonic spectra and synthesized attosecond pulses generated from the highest occupied molecular orbital(HOMO)and those including both HOMO and inner orbitals,it is found that with the increase of laser intensity,the inner orbitals have a significant impact on the minimum structure of HHG spectra generated by the HOMO;when the synthesized attosecond pulse includes the spectral minimum,the inner orbitals have a significant modulation effect on the waveform of attosecond pulses;when the pump-probe angle is changed,the modulation effect of the inner orbitals on the attosecond pulse waveform still exists.关键词
