线型三原子分子在强激光场中多光子激发的李代数方法
Lie algebraic approach to multiphoton excitation of the linear triatomic molecule in intense laser fields
摘要
使用二次非谐振子模型和Magnus近似方法构造了在强激光场下线型三原子分子的振动哈密顿并推导出时间演化算符的代数形式,在此基础上研究了线型DCN分子的跃迁几率随外场的频率和强度的变化关系,表明了多光子跃迁谱的特点.
Abstract
We have constructed the algebraic vibration Hamiltonian and time evolution operator for the linear triatomic molecule in the intense laser fields by using the quadratic anharmonic model and Magnus approximation.The relations between the multiphoton transition probability of the DCN molecule and the frequency and intensity of the external field are discussed.
