Er3+-doped Y3A15012 (YAG) is an interesting system with several useful laser transitions. Laser operation has previously been demonstrated on the 1.6 μm, 2.94 μm, and 561 nm shown in the level diagram of Fig. 1.1–3 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+4 and Yb3+-doped systems. In the present work we have investigated the laser performance at 1.6 μm of Yb,Er codoped YAG epilayers grown on an undoped YAG substrate. |
