钡蒸气中放大自发辐射与参量四波混频的竞争

Competition Between Amplified Spontaneous Emission and Parametric Four-wave Mixing in Barium Vapor

研究了在双光子共振条件下，Ｂａ蒸气中放大自发辐射（ＡＳＥ）与参量四波混频（ＰＦＷＭ）的竞争过程，其机制可归结为ＡＳＥ与ＰＦＷＭ之间的干涉相消。

The amplified spontaneous emission (ASE) and parametric four--wave-mixing (PFWM) in barium vapor are studied under the experimental conditions of two-photon resonance. The mechanisms responsible for this competition can be attributed to the destructive interference between ASE and PFWM.
