中文摘要：
研究了Stark效应对两模双光子J-C模型腔场谱的影响,推导计算出了腔场处于压缩真空态时腔场谱的计算公式和数值结果,讨论了Stark效应和初始场强对腔场谱的影响.发现初始场较弱时,Stark效应主要影响谱线的频率,对峰的强度影响不大;初始场n1^-=n2^-≥2后,Stark效应对主峰有较强的强化作用,对边峰产生抑制作用;在初始场较强时,对谱强度的影响显著.改变Stark移动参数和初始场的强度,可得到各式各样的腔场谱结构.
英文摘要：
The cavity field spectrum of an atom interacting with two-mode squeezed vacuum fields in the presence of Stark shift is investigated. The expression of cavity field spectrum and some numerical results are presented. The effects of Stark shift and initial field intensity on the spectrum structure are discussed. It is found that the peak positions are sensitive to the Stark-shift while the peak heights are not under the condition of weak initial fields.When n1^-=n2^-≥2, the central peak of each mode rises and the other peaks reduce along with the accretion of the Stark-shift coefficients. Various spectral structures may be gained by changing of the Stark-shift coefficients or initial fields.
