摘要: 使用二阶对称分拆光谱方法和一维短程势原子模型对强光辐照下原子的高次谐波谱进行了重新计算 ,第一次实现了强场方程解的边界完备性 ,从而获得了更为清晰的谐波谱和展宽的谐波平台.An exact solution of the intense-field Schr dinger equation is obtained by using the 1D short-range potential model and symmetrically splitting time-evolution operator spectral method. This solution is the first one defined in the full space without any pre-assumed boundary condition. A novel high-order harmonic spectrum is computed based on our wavefunctions. It is found that this spectrum displays clearer harmonic peaks and a wider plateau than that predicted by I p+3.2U p.Abstract: symmetrically splitting operator method; high-order harmonics; intense laser field;
