The {sup 4}I{sub 13/2}-{sup 4}I{sub 15/2} laser action in Er{sup 3+}:Y{sub 3}Sc{sub 2}Ga{sub 3}0{sub 12} (Er:YSGG) at room temperature is described. The authors obtained 1.643 {mu}m laser action from a 1cm long 0.7%Er(3%Yb,1%Cr):YSGG crystal with a 20mJ pump threshold and an 8% slope efficiency utilizing an Er:glass 1.532{mu} pump laser. Further work is in progress to improve the Er:YSGG laser performance.
