摘要
对高功率光子晶体光纤激光器温度分布问题进行了理论研究.在分析光纤热产生机理和结构的基础上,建立了双包层光子晶体光纤激光器稳态切面温度分布简单模型,数值模拟了光纤径向的温度分布、纤芯温度和纤芯-表面温差与纤芯热负载的关系,研究了光纤结构对温度分布的影响;并就激光器光纤泵浦端面的冷却方案进行讨论,数值模拟了外界对流系数不同时纤芯温度的大小.结果表明:对高功率光子晶体光纤激光器采用风冷和水冷的方法可以降低热效应的影响.
Temperature distribution in high power photonic crystal fiber laser is analyzed through the thermal conductive equations. It presentes a steady thermal model of the photonic crystal fiber laser,which is applied to calculate the heat distribution in different fibers at various thermal load. The cooling method of the pump-end is investigated. The results show that air-cooling and water-cooling can significantly reduce the influence of the thermal effect of the high power photonic crystal fiber laser.
