raman gain spectrum

基本解释

The essential theory, Raman gain spectrum, gain characteristics, the configuration and pump sources of the FRA are analyzed.
研究FRA的基本原理，喇曼增益谱，增益特性和结构模型，介绍FRA的泵浦源；
Due to the role of stimulated Raman scattering, Raman gain spectrum is superposed over the conventional MI gain spectrum in optical fibers.
由于受激喇曼散射的作用，使得喇曼增益谱叠加到光纤中的调制不稳定性增益谱上。
Comb-like spectrum lines of cascade Brillouin scattering appear with the saturation of second order Brillouin scattering under Raman gain effect in experiment.
在拉曼增益的作用下，随着二阶布里渊散射的饱和会出现级联的多阶布里渊散射，形成梳状光谱。
