Abstract

The 1.645 (mu) laser action in Er³⁺:Y₃Al₅O₁₂ (Er:YAG) at 300 K was studied using the 1.532 micrometers Er:glass laser for excitation. Laser action was with Er concentrations ranging from 0.5% to 4%. Slope efficiencies as high as 40% were obtained with 0.5% Er:YAG. Laser threshold results indicated that for this Er concentration range upconversion losses were small (negligible for 0.5% Er).
