Evaluation of femtosecond laser-induced breakdown spectroscopy system as an offline coal analyzer

Abstract Developments in femtosecond laser induced breakdown spectroscopy (fs-LIBS) applications during the last two decades have further centered on innovative métier tie-in to the advantageous properties of femtosecond laser ablation (fs-LA) introduced into LIBS. Yet, for industrially-oriented app...
