| 摘 要： | 本文应用量子电动力学理论,研究了强度依存耦合的二能级原子与单模光场相互作用系统中,光场强度对原子共振荧光的影响.证明了系统的共振荧光仍有三峰带结构,光场强度的增加,将使三峰带结构更加明显,但当光场强度很大,使得本征谱分裂值等于一个激光光子能量时,三峰带结构变为双峰带结构,而且边峰带由单光子跃迁变为双光子跃迁.

| Abstract: | In this paper,the authors make a thorough study of the field strength effect on atom resonance fluorescence in the intensity-dependent coupling system of two-level atom and single mode field,by quantum electrodynamics theory.It is proved that three-component spectrum still exists in resonance fluorescence;and the structure is getting even more apparent when field strength is increased.But three-peak-structure becomes two-peak-structure when field strength is so great that proper spectrum divided value equals one laser photon energy,and single photon transition becomes two photons transition in the side peak. |
