我们报道了s偏振，相对论强度的皮秒激光脉冲辐照固体靶的快电子输运和发射模式。一束多MeV电子被发现沿着激光偏振方向的目标表面传输。将该光束的空间强度和能量分布与沿沿着激光传播轴产生的光束进行了比较。结果表明，即使峰值激光强度比相对论阈值高一个数量级，激光极化仍然在电子能量输运中起着重要的作用。3D粒子模拟的结果证实了这一发现。定向射束发射的表征对于需要有效能量转移的应用是重要的，包括二次光子和离子源的开发。
We report on fast electron transport and emission patterns from solid targets irradiated by s-polarized, relativistically intense, picosecond laser pulses. A beam of multi-MeV electrons is found to be transported along the target surface in the laser polarization direction. The spatial-intensity and energy distributions of this beam are compared with the beam produced along the laser propagation axis. It is shown that even for peak laser intensities an order of magnitude higher than the relativistic threshold, laser polarization still plays an important role in electron energy transport. Results from 3D particle-in-cell simulations confirm the findings. The characterization of directional beam emission is important for applications requiring efficient energy transfer, including secondary photon and ion source development.
