标题： Analytical approach of Brillouin Amplification over threshold

摘要： 我们报告了一个精确的闭合形式解析模型，用于计算考虑了耗尽泵浦区域中材料损耗的布里渊光纤放大器的增益。通过数值和实验验证，我们确定了该操作模型在其相关参数和泵浦区域方面的限制。因此，我们的结果使得在弱泵浦、高增益和饱和区域中运行的布里渊光纤放大器的性能预测变得准确。 显示英文摘要

摘要： We report on an accurate closed form analytical model for the gain of a Brillouin fiber amplifier that accounts for material loss in the depleted pump regime. We determined the operational model limits with respect to its relevant parameters and pump regimes through both numerical and experimental validation. As such, our results enable accurate performance prediction of Brillouin fiber amplifiers operating in the weak pump, high gain, and saturation regimes alike.
