摘要
通过数值求解一维短程势含时薛定谔方程,研究了不同频率激光作用下,原子的电离几率,束缚态粒子数布居和谐波辐射随激光强度的变化.结果表明,谐波次数和强度随原子电离几率的增大而增加,基态粒子数布居与电离几率之间具有反比关系,都吴现出强烈振荡的性质.结果表明,高次谐波主要是从连续态到基态的跃迁产生的.
Abstract
By solving the one dimension short range time dependent Schrodinger equation, the ionization probability, population of bound states and harmonic spectra of atom under different laser intensities are studied. It shows that the ionization of atom is good for harmonic generation. Harmonic emission is generated from the jump of electrons from continum states to the ground state, both the ionization and population are oscillating, but with different directions.
