Description/Abstract

Er3+-doped Y3Al5O12 (YAC) is an interesting system with several useful laser transitions. Laser operation has previously been demonstrated on the 1.6µm, 2.94µm, and 561nm shown in the level diagram. Co-doping with Yb3+ allows these transitions to be pumped on the strong, diode compatible absorptions at 940 and 970 nm. Low-loss YAG waveguides grown by liquid-phase epitaxy have operated as low threshold lasers in Nd3+ and Yb3+-doped systems. In the present work we have investigated the laser performance at 1.6µm of Yb,Er codoped YAG epilayers grown on an undoped YAG substrate
