We report the first implementation of a 2 microm thulium fiber laser in a Laser-Induced Breakdown Spectroscopy system. Emission from plasma on copper samples was analyzed from 200 to 900 nm. The low ablation fluence (<100 J.cm(-2)) and 200 ns pulse duration lead to a plasma with neither continuum emission, nor air emission in the near-infrared region.
我们报告了在激光诱导击穿光谱系统中首次实现的2微米掺铥光纤激光器。对铜样品上等离子体在200至900纳米范围内的发射进行了分析。低烧蚀通量（<100 J.cm(-2)）和200纳秒的脉冲持续时间导致等离子体在近红外区域既没有连续发射，也没有空气发射。
