| 摘 要： | 通过数值计算求解含时的薛定谔方程,研究了单个激光脉冲作用下4个不同势函数对应的一维模型氢原子产生的高次谐波,并将其与三维真实氢原子的高次谐波比较。结果表明:势函数势阱的形状对一维模型氢原子的高次谐波强度产生较大影响,但是谐波的截止位置不变。

| Abstract: | By solving the time-dependent schrodinger equation numerically,the high-order harmonic generated from one-dimensional model hydrogen atom corresponding to 4 different potential functions is studied in this paper under the function of a single laser pulse and compared with the high-order harmonic of real three-dimensional hydrogen atoms too.The result shows that the cut-off positions of high-order harmonic are same,but the harmonic intensity of one-dimensional model hydrogen atom is varied with the shape of ... |
