摘要: 采用二维渐近边界条件,将任意极化激光与原子相互作用的二维含时SchrÖdinger方程无穷空间初值问题转化为有界空间的初边值问题,近而将截断后的初边值问题离散成线性正则方程组,而后利用辛算法求解正则方程得到含时波函数.最后利用含时波函数求得高次谐波谱,证明二维渐近边界条件和辛算法是合理而有效的.

关键词: 二维渐近边界条件, 辛算法, 任意极化, 高次谐波

Abstract: 2-dimensional(2-D)asymptotic boundary condition(ABC) of 2-D time.dependent SchrOdinger equation (TDSE)for atoms in an arbitrary polarized laser field is investigated.The condition is obtained bv means of Fourier transformation,and the 2-D TDSE is discretized into a linear canonical equation solved via symplectic algorithm.An arbitrary polarized laser。atom interaction is also investigated.Calculated h讪order harmonic generation(HHG)spectra in good agreement with theoretical results.

Key words: 2-dimensional asymptotic boundary condition, symplectic algorithm, arbitrary polarization, high-order harmonic generation
