The generation and transport of fast electrons play an important role in intense laser interaction with dense plasma. Here, we experimentally study fast electron generation using a planar aluminum target obliquely irradiated at a large incident angle by an ultrashort high-temporal-contrast relativistic laser pulse. Simulations show that for near-relativistic laser intensities, s-polarized lasers above a certain energy threshold can generate energetic electrons () with a high yield, which is different from the case of low laser contrast. It is also shown that the most energetic electrons are emitted along the target's surface and accelerated to high energies. The key features of the acceleration regimes of lasers with different polarizations are also given.

高強度レーザーと高密度プラズマの相互作用において、高速電子の生成と輸送は重要な役割を果たす。本研究では、超短パルス・高時間コントラストの相対論的レーザーを大きな入射角で斜め照射した平面ターゲットを用いて、高速電子生成を実験的に研究した。シミュレーションにより、準相対論的レーザー強度において、s偏光レーザーは特定のエネルギー閾値以上で高収量の高エネルギー電子()を生成できることが示され、これは低時間コントラストの場合とは異なる。また、最も高エネルギーの電子はターゲット表面に沿って放出され、高エネルギーまで加速されることが示された。さらに、異なる偏光における加速機構の主要な特徴も明らかにされた。
