摘要
本文主要从速率方程出发,分析了光纤损耗和自发辐射对线形腔掺镱双包层光纤激光器的影响。通过数值模拟,结果表明光纤损耗对激光阈值、激光增益、输出功率都有影响,而自发辐射主要对激光输出功率产生一定的影响。从而为光纤激光器的优化设计提供理论依据。
In this paper, the affects of loss and spontaneous emission to output characteristics of on Yb^3＋ - doped double - clad fiber lasers by numerical analysis.And it is found that the distribution waster along the fther with emission are effect the threshold, the gain character and the output power, but spontaneous are effect the output power, And which is the theoretical basis for optimized design of fiber laser.
