PRODUCTION OF POLYCRYSTALLINE TRANSPARENT YAG CERAMIC FOR SOLID LASER

摘要

PURPOSE: To relatively easily produce transparent YAG ceramic having satisfactory optical characteristics by adding various laser beam emitting elements. ;CONSTITUTION: Lanthanides and Cr and/or Ti are added to Al₂O₃ powder having ≥99.9wt.% purity and 0.1-5μm primary particle diameter and Y₂O₃ powder having ≥99.9wt.% purity and 0.01-2μm primary particle diameter, and 50-20,000ppm one or more among YF₃, AlF₃, NaF, MgF₂, CaF₂ and LiF are further added as a sintering aid. They are kneaded, molded and fired at 1,600-1,850°C.;COPYRIGHT: (C)1993,JPO&Japio
