| 中文摘要: |
| 利用三态模型和含时波包法,研究了三态阶跃型K2分子在泵浦—探测激光场中场强、波长对光电子能谱Autler-Townes (AT)分裂的影响.首次量化了AT分裂的峰移和间距.共振时光电子能谱为对称双峰,失谐时为不对称双峰.AT分裂间距随泵浦场强增强而增大,但不随探测场强改变而改变.AT分裂间距因泵浦波长不同而不等,但不因探测波长不同而改变.随着泵浦波长偏离共振,光电子能谱逐渐由双峰变为单峰. |
| 英文摘要: |
| The effects of laser intensities and laser wavelengths on Autler-Townes (AT) splitting of photoelectron spectra of three-level ladder K2 molecule driven by a pump-probe pulse was investigated via employing the time-dependent wave packet approach.Their effects on peak shift and AT separation was quantified by using an analytical fitting function.The AT separation increases with pump intensities,but does not vary with probe intensities.The AT separation changes with pump wavelengths,but does not change with probe wavelengths.The double peaks are transformed into one peak progressively as the pump is detuned from the resonance. |
