The 1.645{mu} laser action in Er{sup 3+}:Y{sub 3}Al{sub 5}O{sub 12} (ERYAG) at 300 K was studied using the 1.532{mu}m 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).
