采用PIC （particle-in-cell）模拟研究了超短强激光脉冲斜照射层流光栅结构目标时产生的高谐波。在不同入射角的激光脉冲中，由于谐波分量对入射角的依赖性强，产生了强烈的近表面谐波。与正态入射不同，谐波的空间分布主要受等效电偶极子（OEED）的振荡和空间调制因子的影响，而不是受电流光栅方程的影响。谐波发射强度比正入射时强，这与等效电偶极子的取向有关。此外，当入射角增大（如45°~ 60°）时，近表面谐波均受到明显抑制。采用PIC （particle-in-cell）模拟研究了超短强激光脉冲斜照射层流光栅结构目标时产生的高谐波。在不同入射角的激光脉冲中，由于谐波分量对入射角的依赖性强，产生了强烈的近表面谐波。与正态入射不同，谐波的空间分布主要受等效电偶极子（OEED）的振荡和空间调制因子的影响，而不是受电流光栅方程的影响。谐波发射强度比正入射时强，这与等效电偶极子的取向有关。此外，当入射角增大（如45°~ 60°）时，近表面谐波均受到明显抑制。
High harmonic generation (HHG) by ultrashort intense laser pulse obliquely irradiating a laminar grating-structured target is studied by PIC (particle-in-cell) simulation. For different incident angles of laser pulse, the intense near-surface harmonics is observed due to the strong dependence of harmonic components on the incident angle. Unlike the case of a normal incidence, the spatial distribution of harmonics is mainly dominated by the oscillation of equivalent electric-dipole (OEED) and spatial modulation factor rather than by the current grating equation. The intensities of harmonic emission are stronger than that in the case of a normal incidence, which is associated with the orientation of equivalent electric-dipole. Furthermore, when the incident angle becomes larger (such as 45°−60°), the near-surface harmonics are all observably restrained.High harmonic generation (HHG) by ultrashort intense laser pulse obliquely irradiating a laminar grating-structured target is studied by PIC (particle-in-cell) simulation.
