Outline of Final Research Achievements

For next generation high power optical devises, we developed rare earth(Yb)-doped transparent Al2O3 polycrystalline ceramics. Pulsed electric current sintering, which enables densification at lower temperature and shorter sintering time, was used for sintering, and the resultant optical properties, crystal structure, and microstructure were analyzed. From this study, we obtained high quality Yb(0.2 at.%):Al2O3 polycrystalline ceramics with in-line transmittance of 55% without any second phases. The average grain size was about 200 nm, and Yb elements were observed to segregate along the grain boundaries. On the basis of the present results, we will optimize the powder-processing methods and sintering conditions for obtaining further high doping concentrations and optical properties in the future.
