摘要

用有限元软件COMSOL Multiphysics对锗芯光纤的CO2激光退火温场分布进行仿真，比较了不同的光纤轴向移动速度和激光功率对锗芯光纤加热区温场分布的影响，初步得出了在不同光纤轴向移动速度条件下对应的较合适的激光功率.对于内径和外径分别为80 μm和300 μm的锗芯光纤，当轴向移动速度为4 mm/s、8 mm/s、12 mm/s、16 mm/s、20 mm/s时，对应较合适激光功率分别为1.5 W、2.0 W、2.5 W、3.5 W、4.0 W.该仿真工作为CO2激光退火优化锗芯光纤性能实验提供了理论依据.

Abstract

The temperature feld distribution of Ge core fber in the process of CO2 laser annealing is simulated by using COMSOL Multiphysics. The influences of laser power and fber moving velocity in axial direction on the temperature feld distribution in the laser heating zone are simulated. Accordingly, the proper laser powers corresponding to different moving velocities of fber are preliminarily obtained. For the Ge core fber with the inner diameter of 80 μm and outer diameter of 300 μm, the proper laser powers corresponding to the axial movement velocities of 4 mm/s, 8 mm/s, 12 mm/s, 16 mm/s and 20 mm/s are 1.5 W, 2.0 W, 2.5 W, 3.5 W, and 4.0 W, respectively. The simulation of the paper provides a theoretical basis for optimizing the performance of the Ge core fber by CO2 laser annealing.

Key words： laser power; CO2 laser; temperature feld distribution; Ge core fber; axis movement velocity of fber
