1999年 1 1月美国物理学会等离子体部会议上 ,有三个小组独立宣布 ,他们可用超短激光脉冲照射固体箔靶的小点 ,产生高能离子束流。劳仑斯·里弗莫尔国家实验室报道 ,用“拍瓦激光器”单脉冲产生 3× 1 0 1 3个质子 ,其能量高达 50 Me V。密西根大学的一个小组报道 ,用一台面太? In January 1999, at the meeting of the plasma division of the American Physical Society, three groups independently announced that they could irradiate the dots of the solid foil target with ultra-short laser pulses to generate a high-energy ion beam. Lawrence Livermore National Laboratory reported that using a “pulsed laser” single pulse to produce 3 × 1 0 1 3 protons, the energy of up to 50 Me V. A team at the University of Michigan reported that using a table too?
