【摘要】 本文通过数值分析对线形腔LD泵浦掺镱的双包层光纤激光器进行研究,分析了不同泵浦方式下的泵浦光、激光输出功率和增益特性在光纤中的分布。结果表明,双端非对称泵浦比较适合高功率光纤激光器。进一步又研究双端非对称泵浦输出功率与光纤长度及腔镜反射率的影响,为提高光纤激光器的输出功率提供了理论和实验依据。更多还原

【Abstract】 LD Pumped Yb 3+ -double lasers with linear cavity has been studied in this paper,The distribution of pump light and laser’power and the gain character along the fiber with different pump mode has been researched on by means of numerical analysis,The results show that double-end-unsymmetry-pumped is the optimum for high power fiber lasers.And research on the relation of output power with pump power,as well as the effects of fiber length and cavity reflectivity on output power.It will be helpful for improving the power of fiber lasers in theories and experiments.更多还原
