给出了超强短脉冲激光系统与金属靶相互作用产生多电荷重离子加速的实验证明。铝离子被加速到12 MeV/u(总能量324 MeV)。据我们所知，这是迄今为止报道的由200TW级钛宝石激光系统的10J激光能量产生的重离子加速情况下的最高能量。此外，由于超高强度的激光场类似于10(21)W cm(-2)，加速离子几乎完全剥离，具有高电荷质量比(Q/M)。(C)2013 AIP出版有限责任公司。
Experimental demonstration of multi-charged heavy ion acceleration from the interaction between the ultra-intense short pulse laser system and the metal target is presented. Al ions are accelerated up to 12 MeV/u (324 MeV total energy). To our knowledge, this is far the highest energy ever reported for the case of acceleration of the heavy ions produced by the < 10 J laser energy of 200 TW class Ti: sapphire laser system. Adding to that, thanks to the extraordinary high intensity laser field of similar to 10(21) W cm(-2), the accelerated ions are almost fully stripped, having high charge to mass ratio (Q/M).
