| 摘 要： | 在理论上研究了相干、非相干泵浦的常规三能级激光器的稳态和噪声行为，指出：在相干、非相干泵浦率与激光下能级自发辐射率可以比拟的激光非优化区，相干、非相干泵浦常规三能级激光器的输出光场都呈现亚泊松统计，但只有相干泵浦情况由于量子相干效应能产生无粒子数反转亚泊松激光，且噪声压缩水平高于非相干泵浦情况。 |
| 关 键 词： | 无粒子数反转 亚泊松统计 泵浦 激光 量子论 |

| Abstract: | We discuss the steady-state and quantum noise behaviors of coherently or incoherently pumped conventional three-level lasers. It shows that the sub-poissonian statistics can be predicted in the regime where pumping rates can be comparable with the spontaneous rate of lower lasing level and lasing is not optimal. But only for coherently pumped case, lasing without inversion can occur and noise squeezing is increased because of quantum-interference effect. |
| Keywords: | lasing without inversion sub-poissonian statistics |
