一维模型原子高次谐波特性研究

Characteristics of high order harmonic generation of one-dimensional model atom

通过数值计算求解含时的薛定谔方程,研究了在隧道电离区域16个激光脉冲作用于不同势阱势函数对应的一维模型原子产生的高次谐波特性,结果表明:在隧道电离区域势函数势阱的形状对一维模型原子的高次谐波强度产生较大影响,同时谐波的平台宽度的高阶区域也受到势函数的影响。

By solving time - dependent Schr^dinger equation numerically, we investigate the high or- der harmonic generation （HHG） of one - dimensional model atoms with different model potentials pumped by 16 cycle periods intense laser field. Our results show that the intensities of HHG and the HHG plateau are all affected by potential well.
