Polycrystalline, transparent YAG (Y{sub 3}Al{sub 5}O{sub 12}) ceramics were fabricated by a solid-state reaction method using high-purity Al{sub 2}O{sub 3} and Y{sub 2}O{sub 3} powders. The mixed powder compacts were sintered at 1,600 to 1,850 C for 5 h under vacuum. Optical transmittance in the region between the ultraviolet and infrared wavelengths for YAG ceramics (1 mm thick) sintered at 1,800 C was similar to that for a YAG single crystal.
