| 摘 要： | 利用微扰理论和数值研究方法,讨论了调频光场作用下"激发-电离"物理模型中失谐量对双光子电离光电子谱特性的影响.结果表明,失谐量影响激发态的粒子在缀饰态上的选择性布居,以此对双光子电离光电子谱的特性起到了调制作用.从研究结果可以看出,正失谐有利于将粒子布居在下缀饰态,而负失谐则有利于将粒子布居在上缀饰态.

| Abstract: | The effects on properties of the two-photon ionization photoelectron spectra in excitation-ionization scheme under frequency-modulated fields by detuning are studied by means of perturbation theory and numerical calculation method. It shows that the photoelectron spectra can be modulated by the detuning. The modulation is based on the selective population dressed states of the excited state,and positive detuning leads to selective population of the lower dressed state,while negative detuning leads to select... |
