摘 要: 通过数值求解一维含时薛定谔方程 ,研究了在强激光场中原子及不同尺寸原子团簇的电离几率和光辐射现象。结果表明 ,当外场强度相同时 ,小尺寸原子团簇电离几率小于原子的电离几率 ,可以产生高频率的高次谐波。当原子团簇尺寸较大时 ,其电离几率大于原子的电离几率 ,原子团簇越大 ,电离几率也越大 ,大尺寸原子团簇更易吸收外场能量。 Numerical solution of the schrodinger equation is given to investigate ionization probabilities and optical emission spectra of atoms and clusters of different size in intense laser field. The result indicates that ionization probabilities of small clusters are less than that of atoms, and can produce high frequent harmonic. When the cluster increases in size, its ionization probability also increases. This means that a larger cluster has greater ability to absorb the external field energy.
