| 摘 要： | 利用含时波包法研究并首次量化了强飞秒泵浦-探测激光场中泵浦场强、泵浦波长和脉宽对三态梯型K2分子态布居数的影响.泵浦场强、泵浦波长和脉宽影响Rabi振荡,导致电子态布居数的周期性变化.量化场参数对激发态布居数的影响表明变化频率随着泵浦场强和脉宽的增大而变化.结果为实验上实现分子的光控制和进一步研究K2分子的动力学性质提供了重要参考.

| Abstract: | The effects of pump intensity,pump wavelength and pulse width on state populations of three-level ladder K.2 molecule driven by intense femtosecond pump-probe pulses are investigated and firstly quantified by employing the time-dependent wave packet method.The pump intensity,pump wavelength and pulse width affect Rabi oscillation,which results in the periodical change of the populations of electronic states.The effect of quantization field parameters on population of the excited state shows that the change frequency varies with increasing of pump intensity and pulse width.Results provide an important reference for realizing the molecule optical control in experiment and further study of K2 molecule dynamic properties. |
