| 中文摘要 | 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.
