High Intensity Laser-Atom Interactions (Physics)

激光能量学实验室建议用台式太瓦激光器从理论和实验两个方面研究高强度激光原子相互作用。本文选择了两个相关的课题进行实验研究。第一个是脉冲宽度和带宽对多光子电离率的影响。二是在惰性气体中产生高次谐波。与这些项目同步进行的是，计划通过使用离轴抛物面反射镜来增加激光强度。还建议继续对高强度激光原子相互作用进行理论研究，重点是模型原子从头算波函数的计算和使用。

It is proposed to study high intensity laser atom interactions, both theoretically and experimentally, using the table top terawatt laser at the Laboratory for Laser Energetics. Two related topics have been chosen for experimental study. the first is the effect of pulse width and bandwidth on multiphoton ionization rates. The second is high order harmonic generation in noble gases. In tandem with these projects it is planned to increase the laser intensity through use of an off.axis parabolic mirror. It is also proposed to continue theoretical investigations into high intensity laser.atom interactions, concentrating on the calculation and use of ab initio wave functions of model atoms.
