中文摘要
本研究的目的是研究超强激光在等离子体中的自聚焦,并将物理认识应用于快点火激光聚变的应用。我们成功地观察到了等离子体中的单通道自聚焦以及快电子发射角通孔的变窄。自我聚焦。为了在不损失一般性的情况下证实自聚焦,我们在美国罗切斯特大学的激光系统上进行了实验。使用波长为1053 nm、脉宽为10PSEC、强度为1019W/cm2的激光,观察到了过稠密等离子体中的自聚焦。
英文摘要
The purpose of this research is to study the self-focusing of ultra-intense laser in plasmas and to apply the physics understanding to the application of fast ignition laser fusion. We have succesufuly observed a single channel self-focusing in a plasma as well as the narrowing of fast electron emission angle via. self-focusing. In order to confirm the self-focusing without the loss of generality, we have committed the experiment using the laser system at University of Rochester, U.S.A. Using the laser wavelength 1053 nm, pulse width 10 psec, intensity 1019 W/cm2, the self-focusing in overdense plasmas has been observed.
