摘要:

我们的实验表明,相对温和的超短激光脉冲和结构化的动态等离子体靶的质子到高能量的显着增强的加速。通过在蓝宝石衬底上特殊沉积雪靶并使用精心设计的预脉冲,从5TW激光器中检测到在窄立体角中发射的能量超过21MeV的高质子产额。我们的模拟预测,使用所提出的方案质子可以加速到150兆电子伏以上的能量由100太瓦激光系统。

英文摘要:

We experimentally demonstrate a notably enhanced acceleration of protons to high energy by relatively modest ultrashort laser pulses and structured dynamical plasma targets. Realized by special deposition of snow targets on sapphire substrates and using carefully planned pre-pulses, high proton yield emitted in a narrow solid angle with energy above 21MeV were detected from a 5TW laser. Our simulations predict that using the proposed scheme protons can be accelerated to energies above 150MeV by 100TW laser systems.
