采用辛算法计算并讨论了氢原子在不同峰值强度或不同脉宽下的谐波谱
The time-dependent Schrdinger equation with boundary co nd ition for one-dimentionanl hydrogen atom in intense laser field can be transfor med into inhomogeneous canonic equations by substituting symmetric difference qu otient for partial derivative. The general solutions of the inhomogencous canoni c equations and the particular solutions of the corresponding homogendous ca nonic equations are both generated by symplectic transformation. Therefore t he symplectic method can used to compute them. Moreover the high-order harmonic s and its corresponding bound probability of the one-dimensional hydrogen atom in the laser field are discussed when the laser pulse or the intensity is change d.The results that we obtained are in agreement with other theoretical results.
