Abstract: 
In this work we present the Stark widths (W) of 22 neutral (Cu I) and 100 singly ionized (Cu II) copper spectral lines that have been measured at 18 400 K and 19 300 K electron temperatures and 6.3 × 1022 m -3 and 2.1 × 1023 m-3 electron densities, respectively. The experiment is conducted in the laser-induced plasma - the Nd:YAG laser, operating at 532 nm, was used to produce plasma from the copper sample in the residual air atmosphere at a pressure of 8 Pa. The electron temperature and density were estimated by the Boltzmann-plot method and from the Saha equation. The investigated Cu I lines belong to the 4s-4p′, 4s 2-4p″ and 4p′-4d′ transitions while Cu II spectral lines belong to the 4s-4p, 4p-5s, 4p-4d, 4p-4s2, 4d-4f and 4d-v transitions. Comparison with existing experimental data was possible only in the case of 17 Cu II lines due to a lack of experimental and theoretical values. The rest of the data, Stark widths of 22 Cu I and 83 Cu II lines are published for the first time. © 2013 IOP Publishing Ltd.
