The chamber for the low-pressure laser-induced plasma emission spectrometry, which is used as a tramp element detector was constructed. To guide a high power laser beam into the chamber, the optical system using dielectric mirror and the system using an optical fiber (core diameter:1mm) were tested. To date high power laser beam could not be guided by an optical fiber due to the breakdown of the optical fiber, so the optical system using dielectric minor was used for this experiment. Painted steel plates and Zn plated steel plate were used as a model of scrap iron. By using this system, qualitative information about the surface coatings of the steel plates could be obtained in a short time. Next new excitation source (tramp element detector) was developed. In this experiment, laser beam of medium power from diode-pumped YAG laser was guided by a optical fiber for laser ablation and generated sample atoms were excited by a He glow-discharge plasma. Details of the above-mentioned research were published in paper, in lecture meeting and in international conference.

构建了低压激光诱导等离子体发射光谱分析室，用作杂质元素检测器。为了将高功率激光束引导到腔室中，对使用介质镜的光学系统和使用光纤（芯直径：1mm）的系统进行了测试。迄今为止，由于光纤的击穿，高功率激光束无法被光纤引导，因此本实验采用使用介质镜的光学系统。使用喷漆钢板和镀锌钢板作为废铁模型。通过使用该系统，可以在短时间内获得有关钢板表面涂层的定性信息。接下来开发了新的激发源（杂质元素检测器）。在该实验中，来自二极管泵浦YAG激光器的中等功率激光束由光纤引导进行激光烧蚀，并由He辉光放电等离子体激发产生的样品原子。上述研究的详细内容已发表在论文、讲座会和国际会议上。
