Research Abstract

We developed a novel ZigZag Active-Mirror laser for next generation high power laser systems and demonstrated the laser operation. The laser material is a compact composite ceramics, in which three Yb : YAG layers are combined in series. Output power of 214 W with a slope efficiency of 63% has been demonstrated for cw operation. We also measured temperature dependence of thermal conductivity for 9.8% doped Yb : YAG ceramics. In addition, thermal lens effect and wavefront distortion due to temperature rise have experimentally studied for a single Yb : YAG sample.
