高频强激光场中H－电离特性理论研究
Ionization characteristics of H-in intense high-frequency laser fields
摘要
Abstract
The stability of the multiply charged negative ions, such as H-, H2-, He-, and He2 -, in the high-frequency inense laser fields has been proved in theory for a long time.But no experimental verification has ever been made until now due to various technological challenges.To pave the way for the future experimental test, in this article, by using H-as an example, we study in details its ionization rate and the angular distribution of ion-ized electron with the method of classical phase space ensemble average.It is found that the overall ionization rate of H-is higher than that of the hydrogen atom and no ionization suppression exits in ultra-intense field. And for high-intensity or low-frequency laser fields, the angular distribution of the ionized electrons is quite different from the electron distribution of H-when the laser field is switched off abruptly.关键词
