摘　　要：使用脉冲激光二极管（ＬＤ）泵浦ＹＡＧ激光器作激发源，用ＣＣＤ光学多道分析器采集和分析光谱，进行了激光激发金属微区的发射光谱分析，得到了高信噪比、高动态范围的发射光谱，所测发射波长与标准谱比较符合很好。对方法的应用前景进行了讨论。Emission spectra of several metals stimulated at a tiny spot by an YAG laser pumped by a LD were obtained analyzed by means of a CCD optical multi channel analyzer.The emission spectra collected and analyzed by multi channel with high signal to noise ratio and high dynamic range were obtained,and the wavelengths accord well with the standard spectra of these metals.Application of this method was discussed.
