Multi-Element-Analyse von Stahllegierungen mit Laser-Emissionsspektroskopie

The effects of double pulse bursts from a Q-switch Nd:YAG laser on the laser-induced plasma of steel samples are investigated. Material removal and spectral line intensity are found to be increased significantly by using double pulse bursts in comparison to single Q-switch pulses. The use of double pulse bursts for quantitative microchemical analysis is discussed and results of chemical analysis of low alloy steels are presented.
