研究了绿色激光与固体相互作用中快电子的产生和传播。该实验使用LULI TW激光器（350 fs，15 J）进行，使用掩埋荧光层的K（α）发射来测量电子输运。导体（铝）和绝缘体（塑料）的结果进行了比较与模拟：在塑料中，观察到的快速电子的传播抑制，由于电场成为电子传输的主导因素。
Fast electron generation and propagation were studied in the interaction of a green laser with solids. The experiment, carried out with the LULI TW laser (350 fs, 15 J), used K(alpha) emission from buried fluorescent layers to measure electron transport. Results for conductors (Al) and insulators (plastic) are compared with simulations: in plastic, inhibition in the propagation of fast electrons is observed, due to electric fields which become the dominant factor in electron transport.
