Current status of the research on transparent YAG ceramics as laser hosts from an Italian network

This work describes the results obtained using two different processing systems for the production of YAG based ceramics. One involves the use of commercially available oxide powders (Yb2O3, Y2O3, Al2O3). The other involves the use of Yb-doped Y2O3 (Yb, 9.8%) powders obtained by microwave assisted co-precipitation from salts solution and a commercial alumina (Al2O3). Both systems are processed by wet mechanical mixing of starting oxides and reactive sintering of the obtained mixture
