The thermal interaction of lasers with matter is studied in this work. Using the Green’s function approach, equations governing this interaction are solved semi-analytically. Real conditions, such as the temperature dependence of thermal coefficients, and the surface radiation of matter, were taken into account when solving these equations. A computational code was written in the C programming language to simulate the problem. The proposed method decreases both calculation and simulation times considerably. The proposed method and the developed code are validated by experimental tests, and by means of comparison with another previously-published approach. Since a combination of numerical and analytical methods are used, the developed code is much faster than the numeric software. In addition, the proposed method is more accurate than analytical methods, due to the use of nonlinear boundary conditions. The thermal effects of a CW fiber laser on Al is also investigated.

介绍一种基于格林函数的新型激光与物质热相互作用方法

在这项工作中研究了激光与物质的热相互作用。使用格林函数方法，控制这种相互作用的方程式可以半解析地求解。在求解这些方程式时，要考虑实际条件，例如热系数对温度的依赖性以及物质的表面辐射。用C编程语言编写了一个计算代码来模拟该问题。所提出的方法大大减少了计算和仿真时间。通过实验测试以及与另一种先前发布的方法进行比较，验证了所提出的方法和开发的代码。由于使用了数字和分析方法的组合，因此开发的代码比数字软件快得多。此外，由于使用了非线性边界条件，因此所提出的方法比分析方法更准确。还研究了连续波光纤激光器对Al的热效应。结果sh ...
