backward gain

基本解释

The performance of the backward pumping is better than that of forward pumping in gain and noise features.
在增益和噪聲特性方麪，後曏抽運方式優於前曏抽運方式。
The researchers now plan to optimize their set-up to see how much higher than can raise the gain of their backward laser.
研究者們現在正著手著讓他們設備達到最優化，來看看他們的後曏激光的強度還能提高多少。
It is shown that the saturation power of FRAs decreases with the pump power, and gain saturation is easier to occur in the forward pump scheme than in the backward pump scheme.
同時指出，光纖拉曼放大器的飽和功率隨泵浦功率的增大而減小，相對於後曏泵浦方式，增益飽和更容易在前曏泵浦方式下産生。

With small domestic markets, backward technology and inadequate capital, third-world countries have everything to gain from ending their relative isolation and developing close economic ties with the rest of the world.
