Abstract

CW laser operations of thin-disk lasers with Lu-based oxide ceramics are reported. An output power of 166 W and a slope efficiency of 72.2% were obtained with an Yb:LuAG ceramic disk. We have also successfully demonstrated thin-disk lasers with Yb:Lu2O3 ceramics which were bonded by our soldering and gluing techniques. Slope efficiencies of 60.6% and 55.6% were obtained from a soldered disk and a glued disk, respectively.
