Abstract
The generation properties of Nd3+ in optical pumping of lasers on inorganic liquids based on phosphorus oxychloride and sulfuryl chloride, activated with Nd3+ and UO22+, were studied. In pumping with visible light with λ ≥ 500 nm, uranyl does not affect the generation properties of Nd3+ in laser liquids. Extension of the pumping range to 400 nm leads to deterioration of the laser properties of the liquids and to the formation of U(IV). The uranyl photoreduction in the POCl3–SnCl4–UO22+–Nd3+ system is irreversible. In the SO2Cl2–GaCl3–UO22+–Nd3+ system, reverse oxidation of U(IV) occurs after ceasing the photoirradiation, and in ≈200 h the generation properties of the laser liquid are restored.
