Abstract

In this work, the spectra for plasma glow produced by pulse Nd:YAG laser (λ=1064nm) on Ag and Cu metals in air were analyzed by studying the atomic lines compared with silver and copper strong standard lines. The effect of laser energies of the range 300 to 500 mJ on spectral lines, produced by laser ablation, was investigated using optical spectroscopy. The electron temperature was found to be increased from 1.180 to 1.374 eV, while the electron density increased from 2.50×10¹⁷to 3.97×10¹⁷ cm^-3 with increasing laser energy from 300 to 500 mJ for Ag target. Also for Cu target, the electron temperature was found to be increased from 0.853 to 1.121 eV, while the electron density increased from 0.25×10¹⁷ to 0.26×10¹⁷ cm^-3 with increasing laser energy from 300 to 500 mJ.
