Abstract

Expressions are derived for the probability p(n) that n photons are emitted in a given time in the steady state by a two-level atom, when it is placed in a resonant, coherent, exciting field. The distribution p(n) is shown to be narrower than Poissonian. The ratio [<(Deltan)(2)> - ] is negative and has an absolute maximum value of 3/4. The possibility of observing the sub-Poissonian statistics is discussed briefly.

摘要

当一个二能级原子置于共振、相干激发场中时，推导出了该原子在稳态下在给定时间内发射(n)个光子的概率(p(n))的表达式。结果表明，分布(p(n))比泊松分布更窄。([<(\Delta n)^2> - ]/)的比值为负，其绝对值最大值为(3/4)。简要讨论了观测亚泊松统计的可能性。
