采用一维粒子模拟方法研究了超强圆偏振激光脉冲与固体靶的相互作用。离子在靶前被运动的准稳态静电场反射，获得相对论速度。在1022 W scincm ~ 2的激光强度下，几乎一半的激光能量转移到离子上，得到GeV的离子。研究了激光偏振态和靶材厚度对激光能量转换的影响。结果表明，在相同的激光参数和靶参数下，圆偏振激光脉冲比线偏振激光脉冲能更有效地加速离子。一个单能离子束获得的靶，这是作为一个单一的实体加速。
The interaction of an ultraintense circularly polarized laser pulse and a solid target is studied by one-dimensional particle-in-cell simulations. Ions at the front of the target are reflected by a moving quasisteady electrostatic field and obtain a relativistic velocity. At a laser intensity of 1022W∕cm2, almost half of the laser energy is transferred to ions and GeV ions are obtained. Effects of laser polarization state and target thickness on the laser energy conversion are investigated. It is found that a circularly polarized laser pulse can accelerate ions more efficiently than a linearly polarized laser pulse at the same laser and target parameters. A monoenergetic ion bunch is obtained for the ultrathin target, which is accelerated as a single entity.
