The laser wakefield (LWF) and the relativistic and charge-displacement self-channeling in the comparatively low density plasma were studied. The dynamics of electron plasma wave (EPW) in LWF was experimentally observed at the electron density of 〜10^<16>cm^<-3>. The two dimensional instantaneous image of EPW was also obtained. The asymmetric 2D image was explained by the modified linear theory. These experimental results suggest that the intensity of 〜10^<18>W/cm^2 was achieved in the low density static gas. For the self-channeling, the simple model tells us that the long channel without defocusing could be possible with a tens of TW, ps glass laser system.

研究了相对低密度等离子体中的激光韦克菲尔德、相对论性自沟道和电荷位移自沟道。在电子密度为1000 ~ 1000 μ m时，实验观察到了LWF中的电子等离子体波（EPW）动力学<16><-3>。获得了EPW的二维瞬态图像。用修正的线性理论解释了这种不对称的二维图像。这些实验结果表明，<18>在低密度静态气体中可以获得10 ~ 10^ W/cm ^2的强度。对于自沟道，简单的模型告诉我们，在几十TW，ps的玻璃激光系统中，没有散焦的长沟道是可能的。
