In this paper, plasma is generated from the nano and bulk copper targets by using Nd:YAG laser with a wavelength of 1064 nm, frequency of 6 Hz and pulse duration 9 ns at atmospheric pressure. The Boltzmann plot method was used to calculate the temperature of electrons and the Stark broadening method to calculate the density of electrons in a laser-generated plasma. It was observed that increased in the laser energy from 500 to 800 mJ leads to increased the temperature of electrons from 1.8 to 2.5eV and increased the electrons density from 3.65×10 16 to 4.29×10 16 cm −3 for nano copper plasma while increased the temperature of electrons from 1.2 to 2 eV and increased the electrons density from 2.28×10 16 to 3.24×10 16 cm −3 for the bulk copper plasma.
