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。
The research on the phenomenon of space scattering in pulsed laser machining is an important method to analyze the quality of the laser beam absorbed by the material and improve the machining accuracy. Based on the principle of scattering rate + absorption rate = 1, this paper analyzes experimentally the space scattering phenomenon, the research method of the scattering phenomenon and the experiment collection device, establishes the mathematical model of the space scattering energy. Through the acquisition system and the corresponding software programming, draws the scattering energy distribution Figure The experimental results show that the spatial distribution of scattering energy is approximately one-sphere.
