We report the first implementation of a 2 mu m 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 ( \u3c 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
