Abstract

The dynamics of resonance-enhanced LIBS plasmas in various ambient gases was investigated by time-resolved studies. Results suggest that a larger plume volume was heated in the resonance case. Together with the right ambient gas, the plasma temperature could be sustained to enhance the analyte signal.
