Demonstration of laser oscillation of an Yb-doped Y 2 O 3 composite disk by use of atomic diffusion bonding in room temperature

We demonstrate the laser oscillation of an Yb-doped Y2O3 composite disk by use of atomic diffusionbonding (ADB) in room temperature. The continuous wavelaser power was observed to be 6 W. We also measured the behavior of the wavefrontproduced by ADB.
