Paper Abstract

We investigated the effects of various polishing additives added to cerium oxide slurry on the polishing properties of phosphate laser glass. The results showed that additives could change the polishing efficiency of the slurry and affect the surface quality of the laser glass. After polishing, the surface roughness of the glass increased and even micrometer-scale etch pits formed on the glass surface. The additive with 1.05% by weight LaF 3 improved the polishing efficiency significantly while controlling the surface roughness of the laser glass. From the chemical-reactions perspective, a model was proposed to analyze the polishing mechanism based on the chemical composition and structure of the phosphate laser glass material and on current and previous experimental phenomena.
