1.6 mu m eye-safe emission of a diode pumped Er, Yb co-doped YAG ceramic laser is firstly demonstrated. Operation of the ceramic laser under different ceramic sample lengths, co-doping concentrations and control temperatures were experimentally investigated. A maximum output power of 222 mW was achieved at an absorbed pump power of 8.1 W, corresponding to a conversion efficiency of 2.74%. Laser emission at 1.05 mu m for transition of the Yb3+ ions was also studied on the same ceramic samples. The results clearly show the existence of resonantly energy transfer from the Yb3+ ions to Er3+ ions. (C) 2013 Optical Society of America
