| 摘 要： | 本文用叠代法求得了含弛豫项的广义光学Bloch方程的近似解。与计算机给出的数值积分解的比较表明,一阶叠代解具有足够好的精度。由此得出了上能级占有几率随时间变化的解析表达式及多光子吸收、Bloch-Siegert频移等有用结果。

| Abstract: | Approximate solutions of the feneralized Bloch equations which describe a two-level system interacting with a strong no-rotating field are presented. The approximation is based on an iterative method. The accuracy of solutions is discussed by comparing them with the numerically intefrated solutions. It is shown that the first order iterative solutions have sufficiently good accuracy. Several valuable conclusions on the time-dependence of the occupation probability, the multi-photon absorption, and the Bloch-Siegert shift are drawn. |
