摘要: 在這篇論文中我們利用古典蒙地卡羅方法來探討原子系統與強快速 雷射的交互作用及雷射中磁場效應的貢獻。一般原子再高強度雷射的 照射下會產生High Harmonic Generation現象。此現象在高強度快 速雷射下及考慮雷射磁場下所造成的影響,將是我們探討的問題。
In this thesis, we use Classical Trajectory Monte Carlo method to study the atomic dynamics under short intense pulse and magnetic effect. When an atom is exposed to an intensity laser pulse, it develops a time-dependent dipole moment and radiates a series of odd harmonics of incident laser frequency. This phenomenon of harmonic generation has been observed over wide ranges of laser intensity (e.g.10**13~10**16 w/cm**2 ). However, current laser systems can produce very short (femtoseconds) and high intensity pulses stronger than 10**17w/cm*2*2 Under such high-intensity and short time laser, the dynamics of atom and the effect of the magnetic filed component are important, and not yet well studied.
