在由激光韦克菲尔德机制产生的等离子体波中，观察到了注入电子的加速现象。已测得的最大能量增益为1.6 MeV，最大纵向电场估计为1.5 GV/m。当考虑三维效应时，实验数据与理论预测一致。从加速电子的数量推断的等离子体波的持续时间是1 ps的数量级。
The acceleration of electrons injected in a plasma wave generated by the laser wakefield mechanism has been observed. A maximum energy gain of 1.6 MeV has been measured and the maximum longitudinal electric field is estimated to 1.5 GV/m. The experimental data agree with theoretical predictions when 3D effects are taken into account. The duration of the plasma wave inferred from the number of accelerated electrons is of the order of 1 ps.
