Results of spectroscopic temperature measurements of the laser-induced plasma generated during the beam-on-plate experiment with a 3.8 kW diode-pumped, pulsed Nd:YAG laser are studied. Argon is used as the shield gas. Vertically resolved emission spectra were collected. The broadening of the emission lines are discussed.
