Nahi PY - 2022 VL - 18 IS - 1 SP - 15 EP - 20 JO - Iraqi Journal of Applied Physics المجلة العراقية للفيزياء التطبيقية SN - 18132065 23091673 AB - In this work, emission lines of laser-produced plasmas from three different metallic targets (copper, titanium and nickel) were detected by the optical emission spectroscopy. These plasmas were generated by irradiation of the metallic target with laser pulses of high peak power in room environment. Both electron density and electron temperature were determined for the three targets at different peak laser powers using the ratios of line intensities based on the obtained emission spectra. Electron temperatures were determined in the range 0.34-0.442 eV for copper target at laser power of 70 MW, 0.281-0.418 eV for titanium target at laser power of 60 MW, and 0.35-0.46 eV for nickel target at laser power of 70 MW.
