超冷三能级原子注入微脉塞的光谱性质

Spectrum of the Micromaser Injected with Ultracold Three-Level Atoms

利用双光子 mazer的量子力学主方程 ,建立了谱的形式理论 .通过数值计算 ,研究原子质心动量、腔长、失谐量、原子泵浦速率、腔场衰减速率以及热光子数等因素对双光子 mazer谱的影响 .结果表明 ,双光子 mazer的光谱不仅有展宽 ,而且有频移 .频移既可以是红移的 ,也可以是蓝移的 .

The spectrum of the micromaser injected with ultracold three- level atoms was studied.The ef- fects of the atomic center- of- mass momentum,the cavity length,the detuning,the atomic pumping rate, the cavity decay rate,and the number of thermal photons on the spectrum were examined.Itis shown that the linewidth can be broadened,and the frequency can be blue- shifted or red- shifted.
