摘要

为了分析高功率光纤连续激光束远距离传输到达靶面后对金属板材料的损伤效果，利用强光阵列探测器系统对高功率连续光纤激光聚焦光束经不同距离传输后激光光斑质心抖动进行了实验研究，分析了光斑抖动漂移对远场金属板损伤效果的影响。将实验测得的抖动结果作为激光抖动源进行了有限元数值模拟，并与光斑无抖动情况下的温度分布进行对比。实验结果显示：随着传输距离的增大，抖动漂移的幅度不断增强；在同一传输路径下，水平

方向的抖动偏差量明显低于铅直

方向的抖动偏差；远场光斑因抖动呈现椭圆分布，而激光作用远场金属板后靶面损伤形貌呈椭圆，并出现约20°的偏转。随着传输距离的不断增大，当光斑质心抖动偏移量大于光斑半径时，金属板最高温升下降率达到10%以上。结果表明，高功率连续光纤激光束经远距离传输后光束质量变差，使得激光与靶面耦合效率降低，影响激光远距离损伤金属板效能。

Abstract

In order to analysis the interaction between the metal plate and high-power CW fiber-laser beam through a long distance transmission

the laser beam jitter induced by the interaction on a high-power array detector with a high power CW fiber laser at different distances was researched experimentally

where the effect of the laser jitter on the damage of the metal plate was analyzed. The jitter and jitter-free models of the far-field damage of metal plates were built in simulation

and the temperature distribution between the jitter and jitter-free mode is compared by the finite element method. It shows that the jitter amplitude grows gradually with the increase of the transmission distance. At the same transmission path

the deviation along horizontal direction

is lower than that in the vertical direction

. Due to laser spot jitter

the far-field spot presents elliptical distribution

which leads to elliptical damage morphology on the plate and a beam deflection about 20 °. When the spot centroid offset is greater than the spot radius

the maximum temperature drop rate of the metal plate reaches more than 10% by the original position. The experiments and simulations demonstrate that the high-power CW laser beam quality declined after a long distance transmission which may reduce the energy coupling efficiency and affect the laser material interaction efficiency.
