本文在Yb：YAG激光器实验研究的基础上，对激光束热源进行了模拟。使用UFF 100分析仪测量Trumpf激光头D70发射的真实的激光束功率。建立了基于地质统计学克里格法的热源插值模型。将实验确定的Yb：YAG激光功率强度分布与解析模型和插值分布进行比较，以确定真实的激光束热源分布映射的准确性。最后，对激光加热过程进行了有限元数值模拟，以验证所提方法的有效性。(C)2015爱思唯尔有限公司版权所有。
This paper concerns the modelling of laser beam heat source based on experimental research of Yb:YAG laser. Measurements of the real laser beam power emitted by Trumpf laser head D70 are performed using UFF100 analyser. Developed heat source interpolation model is based on the geostatistical Kriging method. Comparison of experimentally determined Yb:YAG laser power intensity distribution with analytical models and interpolated distribution is carried out in order to determine the accuracy of mapping of the real laser beam heat source distribution. Finally, numerical simulation of laser heating process is performed in finite element method to evaluate the usefulness of presented solutions. (C) 2015 Elsevier Ltd. All rights reserved.
