Liquid laser gain medium containing neodymium ion derivatives can be a candidate to replace solid-state materials to solve the thermal lensing problems of high-power lasers, which has attracted the attention of researchers in this field. This article reports the production, thermal and spectral analysis of two samples of liquid laser gain medium containing 0.3 M Nd3+ salt in deuterium dimethyl sulfoxide (organic solvent) and phosphorus oxychloride (inorganic solvent). Spectral investigation of these active materials shows a decrease in fluorescence intensity in the Nd(TFA)3-DMSO-d6 sample compared to the Nd3+-POCl3-SnCl4 sample. Despite the low fluorescence intensity in the organic solvent versus the inorganic solvent, this sample receives more attention due to the significant reduction of the effects of toxicity and corrosiveness. The results show that the liquid laser gain medium containing neodymium ion derivatives has solved the thermal problems due to better heat transfer. Still, with a minimal gain coefficient of 0.0001 cm-1, it isn't easy to create laser oscillation and the output efficiency reduces
