用粒子模拟方法研究了相对论飞秒激光脉冲与窄薄靶相互作用对离子加速的影响。数值结果表明，当靶的宽度小于激光束腰时，离子在两个静电场的作用下可以在级联中加速。第一场是由激光束的中心部分在靶体前面形成的，它将电子层向内推。远轴激光能量的主要部分沿着靶的边缘传播到靶的背面，并从靶的边缘拉出一些热电子，在靶的背面形成另一个静电场。来自前表面的离子被这两个静电场逐步加速到靶后的高能。模拟结果表明，窄靶的最大离子能量增益约为宽靶的4倍。
Particle-in-cell simulations are performed to study the acceleration of ions due to the interaction of a relativistic femtosecond laser pulse with a narrow thin target. The numerical results show that ions can be accelerated in a cascade by two electrostatic fields if the width of the target is smaller than the laser beam waist. The first field is formed in front of the target by the central part of the laser beam, which pushes the electron layer inward. The major part of the abaxial laser energy propagates along the edges to the rear side of the target and pulls out some hot electrons from the edges of the target, which form another electrostatic field at the rear side of the target. The ions from the front surface are accelerated stepwise by these two electrostatic fields to high energies at the rear side of the target. The simulations show that the largest ion energy gain for a narrow target is about four times higher than in the case of a wide target.
