Paper Abstract

In this paper we explore laser induced breakdown spectroscopy (LIBS) at relatively low energies in the range 10 - 350 tJ. We present measurements ofthe threshold laser energy needed for LIBS and the scaling ofplasma size and crater size with energy. The effects of the laser pulse length and gating of the detector on the LIB spectra are studied and we also assess the use ofmicrojoule LIBS for the identification ofAl alloys.
