摘要
对脉冲激光加工中空间散射现象的研究是分析材料吸收激光束质量，提高加工精度的重要方法。本文根据散射率＋吸收率＝１的原理，实验分析空间散射现象，确定散射现象的研究方法和实验采集装置，建立空间散射能量的数学模型，通过采集系统和相应的软件编程，绘制散射能量分布图。实验结果表明：散射能量的空间分布近似为一球缺。
Studying on spacing scattering phenomena in pulse laser machining is an important method to analyze quality of laser bean absorbed by material and improve machining precision.According to the theory of equation:absorption rate+scatter rate=1,this paper has analyzed the scattering phenomena by experiments,determined ways and collection devices to research it.At the same time,the mathematical models of scattering-energy have been presented and its graphics have been drawn under AUTOCAD by collection system and its soft program.Experimental result shows that the spacing distribution of the scattering-energy is like as segment.
