光子發射譜-
First the emission spectrum of an atom in a grey - body cavity is stuided. the influences of the incident field photon - number distribution, the cavity absorptivity and the system temperature on the atomic emission spectrum are discussed in detail. it is found that the influence of cavity radiation on the atomic emission spectrum could be reduced through diminishing the absorptivity of the cavity and lowering the temperature of the cavity
我們首先研究了灰體腔中二能級原子和型三能級原子的發射譜，詳細討論了入射場光子數分佈、腔體吸收系數以及系統溫度對原子發射譜的影響，指出在實驗上可以通過減小腔體吸收系數、降低系統溫度來減小腔體輻射對原子發射譜的影響。 -
Finally we focus our attention on studying the emission spectrum of two atoms driven by a single - mode field in an ideal cavity. we showed that the atomic emission spectrum is insensitive to the phase of field for the two atoms initially in the coherent superposition state tf / = v2 / 2 ( j +, - ) h ? + } ), when the two atoms is initially prepared in ( fs * } = cos ( 0 / 2 ] +, + ) + sm ( 0 / 2 ) ei ' p -, - ), the atomic emission spectrum is associated with not only the field photon - number distribution and the atomic populations, but also the phases of the field and the atomic dipole
接著考察了好腔中由單模量子場驅動的雙原子發射譜，結果表明初態為的雙原子發射譜與驅動場的相位無關；而初態為的雙原子發射譜不僅與光場的光子數分佈以及原子的布居數有關，而且依賴于光場的相位以及原子偶極矩的相位，並且在適當的條件下，壓縮真空場可將雙原子俘獲在相干疊加態。 -
When the cavity field is initially in photon number state or mixed state, the emission spectrum of the two - level atom has nothing to do with the phase of the atomic dipole. if the cavity field is initially in the coherent superposition of photon number state, the emission spectrum of the two - level atom exhibits phase sensitivity. if a a - type three - level atom is initially in the coherent superposition of its two non - degenerate lower states, the emission spectrum depends on the phase of the atomic dipole
證明了初始時刻驅動場處于光子數態或者光子數的混合態時，二能級原子發射譜與原子偶極矩的相位無關，只有當驅動場初始時刻處于光子數的疊加態時，原子發射譜才依賴于原子偶極矩的相位；而初始時刻處于兩個下能態相干疊加態的型三能級原子發射譜對原子初態的依賴關系卻不受單模驅動場的影響。
