原子系统量的涨落与亚泊松激光的关系

RELATIONS BETWEEN SUBPOISSONIAN LASING OUTPUT AND FLUCTUATIONS OF ATOMIC SYSTEM PARAMETERS

此文在理论上研究了非相干泵浦的常规三能级激光器输出光场和原子系统的稳态和噪声涨落行为，指出：在泵浦率与激光下能级自发辐射率可以比拟时，输出光场呈亚泊松统计，这源于原子系统参量涨落的非经典特性。

We discuss the Steady-stste and noise - fluctuation properties of laser outPUt and atomicsystem parameters of incoherently pumped conventional three-level laser for which thesubpoissonian statistics can be predicted and originates from nonclassical properities of atomicparameter fluctuations, in the regime where pumping rates can be comparable with thespontaneous rate of lower lasing level.
