本文研究在呈指数衰变的驱动场的作用下,二能级原子系统算符间的对易关系,及所满足的Bloch方程的解,通过解Laplace变换后的差分方程,计算出二能级原子系统的瞬态共振荧光光谱,并对计算结果进行分析与讨论。The commutation relation and quantum mechanical Langevin equations for a two-levef system is evaluated at first. Then, the instantaneous fluorescence spectrum of atomic system driven by an exponentially decaying field is calculated.
