作者从理论和实验上证明了如何利用啁啾强场超快激光脉冲的时变相位或频率来控制多原子分子中不同离子态的电离产额。结果被解释在两种类型的非绝热动力学之间的竞争：多光子共振和内部转换。
The authors show theoretically and experimentally how the time-varying phase or frequency of a chirped strong-field ultrafast laser pulse can be used to control the ionization yield to different ionic states in a polyatomic molecule. The results are interpreted in terms of a competition between two types of nonadiabatic dynamics: multiphoton resonance and internal conversion.
