介绍了用壁裂算子求解超短激光场中原子系统函数的方法。此法比标准差分法给出更准确的模拟结果。许多结果可从演化的波函数中得到。作为例子,计算了一种简单原子的电离风率和谐波发射谱。 相似文献

The high backing pressure argon gases adiabatically expand into vacuum through a pulsed gas jet to nucleate into large clusters. The clusters were heated by a 45fs, 2.3×1016 Wcm-2 Ti: sapphire laser. The high energy of the ions produced in the cluster explosion was measured using time-of-flight spectrometry. The maximum and average kinetic energy of the ions were 0.2MeV and ~12.5keV, respectively, indicating that the femtosecond laser interactions with argon clusters are more energetic than interactions with atoms and molecules. 相似文献
