摘要
建立了百纳秒级单频脉冲光纤激光极限输出功率的理论模型,分析了影响Yb3+掺杂的硅玻璃光纤和磷酸盐光纤最大输出功率的影响因素,计算结果表明影响硅玻璃光纤极限输出功率的因素有抽运光亮度、透镜效应和受激布里渊散射(SBS)效应,而对于磷酸盐光纤除了上述三种因素外还包括纤芯的熔化。在单频脉冲极限输出功率方面磷酸盐光纤的性能要优于硅玻璃光纤。
Abstract
A model of power limit of hundred-nanosecond single-frequency pulsed fiber lasers established, by which the maximum extractable power of ytterbium-doped silica fiber and phosphate fiber are analysed. Numerical results show that the power of Yb3+-doped silica fiber sources is limited by pump brightness, lens effect and stimulated Brillouin scattering (SBS), while, for Yb3+-doped phosphate fiber sources, melt of the core is also included. On the aspect of maximum extractable power of single-frequency pulsed laser, phosphate fiber is better than silica fiber.
