分子在强光场中空间排列的倾向
The propensity of molecules to spatially align in intense light fields
摘要：
分子沿强脉冲光场的偏振矢量空间排列的倾向与容易获得的参数（分子偏振度、转动惯量、光的峰值强度及其脉冲持续时间）有关。现在可以预测哪些分子可以在空间上排列，以及在什么情况下，在强光照射下。占增强电离和超极化率，它表明，{ \it所有}分子可以对齐，即使是那些最小的静态极化率，当受到最短的可用激光脉冲（足够的强度）。
英文摘要：
The propensity of molecules to spatially align along the polarization vector of intense, pulsed light fields is related to readily-accessible parameters (molecular polarizabilities, moment of inertia, peak intensity of the light and its pulse duration). Predictions can now be made of which molecules can be spatially aligned, and under what circumstances, upon irradiation by intense light. Accounting for both enhanced ionization and hyperpolarizability, it is shown that {\it all} molecules can be aligned, even those with the smallest static polarizability, when subjected to the shortest available laser pulses (of sufficient intensity).
