摘要
采用二维渐近边界条件和辛算法数值求解激光与多势阱系统相互作用的二维含时Schr(o|¨)dinge方程的无穷空间初值问题.计算二维多势阱系统分别在线偏振激光和圆偏振激光作用下的谐波发射,得到不同模型发射谐波谱的特点,说明多势阱环境有利于高次谐波的发射.
The two-dimensional time-dependent Schrödinger equation (TDSE) of laser pulse interacting with a two-dimensional multiwell system is solved by using the two-dimensional asymptotic boundary condition (ABC) and symplectic algorithm. The high order harmonic generation(HHG) of the system in the laser field has been calculated, and the characteristics of HHG under different polarized laser field has been analyzed.
