摘要

文章历史:收到2021年9月10日收到修订形式2021年10月22日接受2021年10月23日在线提供2021年11月12日高功率光纤激光器需要有效冷却以避免热损伤。在光纤激光器的设计过程中，需要对光纤中的温度分布进行估计。通过求解圆柱几何下的稳态热方程，推导出任意层数的多层光纤中温度径向分布的实用公式。热源位于一个或多个圆柱形域中。通过与八角形双包层纤维、空气包层纤维、非均匀微结构纤芯纤维等典型应用实例的静态传热模拟对比，验证了解析公式的有效性。据报道，即使在不完全是圆柱形域的情况下，精度也足以用于实际使用。

Formula for temperature distribution in multi-layer optical fibres for high-power fibre lasers

Article history: Received 10 Sep. 2021 Received in revised form 22 Oct. 2021 Accepted 23 Oct. 2021 Available online 12 Nov. 2021 High power fibre lasers need to be cooled efficiently to avoid their thermal damage. Temperature distribution in fibre should be estimated during the fibre laser design process. The steady-state heat equation in a cylindrical geometry is solved to derive a practical formula for temperature radial distribution in multi-layered optical fibres with arbitrary number of the layers. The heat source is located in one or more cylindrical domains. The validity of the analytical formula is tested by comparison with static heat transfer simulations of typical application examples including octagonal double clad fibre, air-clad fibre, fibre with nonuniform, microstructured core. The accuracy sufficient for practical use is reported even for cases with not exactly cylindrical domains.
