Using 32.4 mg CuCl2 powder, the CuCl2 aqueous solution with the concentration of 1.62×10-4 is prepared. The CuCl2 aqueous solution plasma is produced by focusing the 1064 nm Q-switched NdYAG laser onto it. The plasma temperature of 1850 K is inferred using Boltzmann plot method, while the electron density of 5.8×1016 cm-3 is obtained from the Stark broadening of the profile of Hα 656.273 nm. Based on experimental results, the laser-induced CuCl2 aqueous solution plasma is verified to be in local thermodynamic equilibrium.
