Vacuum Ultraviolet

Most often the LIBS measurements are carried out in the visible and ultraviolet regions, where majority of the elements have strong emission lines for analysis. However, non-metallic elements like sulfur, phosphorus, halogens, carbon, nitrogen, and arsenic, have their strongest lines in the near vacuum ultraviolet (VUV) spectral region (110 - 190 nm). LIBS laboratory has recently presented an alternative setup for laser-induced plasma measurements in the near VUV down to 130 nm using ICCD detection. Our gas-purged setup has been applied e.g. to identify and classify sulfide minerals at wavelength range from 170 to 210 nm without vacuum chambers.

Mineral Spectroscopy

With laser-induced breakdown spectroscopy semi-quantitative elemental composition and mineral composition of the drill core samples can be obtained by spectral data processing. An example of an yttrium-bearing rock sample shows good correlation between the constructed mineral map (1) and the rock sample surface in photo under normal light (2) and UV light (3) and yttrium distribution map using single LIBS line (4).

Paper Analysis

Material distributions in paper and paper coatings are important factors, which determine the properties and quality of paper. The major advantage of using LIBS to analyze paper is that material distributions can be determined with moderate spatial resolution (~ 0.5 μm) also in Z-direction because every laser shot can be analyzed.


  • LaseREE project is based on investigating and developing on-site methods of laser-spectroscopic analysis from REE bearing rock samples. The research is basic laboratory research, but the target is to investigate the possibilities of laser-based methods as a very quick and cost-efficient on-site analysis. The LaseREE project combines laser-spectroscopic research in University of Jyväskylä, time-gated electronic knowledge of University of Oulu and pulsed laser light production in Tampere University of Technology. The project has been funded by the Academy of Finland in the program “Mineral Resources and Material Substitution (MISU, 2014–2019)". 
  • Laser-in-Situ project aims for development of fast and remote characterization methods for rock topography and mineralogy based on the laser scanning and spectroscopy. The consortium members are Aalto University, Finnish Geospatial Research Institute, University of Jyväskylä and University of Oulu. The project has been funded by the Academy of Finland in the program “Mineral Resources and Material Substitution (MISU, 2014–2019)”
