Application and development of UV laser induced breakdown spectroscopy

Laser induced breakdown spectroscopy (LIBS) is an element analysis technique based on atomic emission spectroscopy and an important research method in the field of elemental analysis. As the excitation source of LIBS analysis, ultra-violet(UV) laser has the advantages of high photon energy and high spatial resolution, so it can effectively improve the ablation efficiency, reduce the fractionation effect and has good application prospects in geological and biological medicine detection. UV laser can also effectively enhance the effect of elemental analysis, and expand the application scope of LIBS technology. The principle and characteristics of ultraviolet LIBS technology were introduced. The application of ultraviolet LIBS technology at home and abroad was discussed. The development trend of ultraviolet LIBS technology was summarized.
