中文摘要：

影响在噪音特征上由拉曼效果导致了一弄空并且有损耗的双泵纤维光参量的放大器(FOPA ) 被调查。考虑拉曼效果，修改联合振幅方程第一被造，然后，拉曼的影响在 Stokes 和反上完成 -- 司烧有不同起始的信号力量的波长进一步被分析。而且， FOPA 获得上的效果也与一样的起始的信号力量和经常的噪音数字(NF ) 被显示出。

英文摘要：

Influence induced by Raman effect on the noise characteristics of a depleted and lossy dual pump fiber optical parametric amplifier （FOPA） is investigated. Taking the Raman effect into account, the modified coupled amplitude equations are fh-stly built, then the influences of Raman effect on the Stokes and anti-Stokes wavelengths with different initial signal powers are further analyzed. Besides, the effect on the FOPA gain is also shown with the same initial signal power and constant noise figure （NF）.
