We have been succeeding in fabrication of highly transparent ceramics with vacuume sitering method and nanocrystalline technology. Femtosceond ceramic lasers and highly efficient cw ceramic lasers were developed with Yb-doped ceramics. A cw Yb3+-doped Y2O3 ceramic laser was demonstrated with the extraction efficiency of 72 %. A modelocked Yb3+-doped Y2O3 ceramic laser were demonstrated with a semiconductor saturable-absorber mirror. The modelocked laser generated 78 MHz and 615 fs pulses. The average power of 420 mW, and the pulse energy of 4.3 nJ at a 2.5 W absorbed pump power.
