超短超强激光脉冲与固体物质相互作用产生高能离子的研究,以其加速场强度比传统加速器高出4个量级的绝对优势而受到国际加速器以及激光专家的广泛关注。但是目前绝大多数实验及理论研究都集中在800nm或者1μm的可见或红外固体激光器。但实际上,决定质子能量的主要有两点: The research of ultrashort superlattice laser pulses interacting with solid matter to generate high energy ions has attracted the attention of international accelerators and laser experts for its absolute superiority of accelerating the field strength by more than four orders of magnitude over traditional accelerators. However, most experimental and theoretical studies have focused on visible or infrared solid-state lasers at 800 nm or 1 μm. But in fact, there are two main factors that determine the proton energy:
