摘要

本文设计了一种新型的激光脉冲能量测试装置。利用它可以测量KJG-1YAG-400A激光焊机的脉冲能量。建立了该装置的热学模型，并进行了热损失分析。得到了器件吸收激光能量后时间与电阻的运行曲线。通过对试验数据的修正，揭示了单脉冲激光能量、脉冲宽度和电流之间的关系，为激光钎焊工艺提供了理论基础和实践经验。

Testing Method and Experimental Studies on Single Laser Pulse Energy

A new type of testing device is designed for energy of laser pulse in this paper. By using it, pulse energy of KJG-1YAG-400A laser welder can be measured. The calorific models have been established for the device, and the analysis of thermal loss has been finished. Running curves have been obtained between time and resistance after the device absorbing laser energy. After test data is amended, the relationship among single pulse of laser energy, pulse width and current has been revealed, which provided theoretical foundation and practical experience for the laser brazing process.
