Paper Abstract

We are developing rod-type all solid-state laser with average power more than 10 kW as a tool for high speed and highly precise material processing such as cutting and welding. We developed a rod-type all solid-state laser system with average power of 3 kW level and succeeded in attaining an average power of 3.3 kW with multi head configuration with combined mode of CW and QCW operation. We also obtained electrical- optical efficiency of 19% in CW operation and that of 17% in QCW operation in the region of average power of 0.8 kW to 1.0 kW.
