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. In this year, we developed rod-type all solid-state laser system with average power of 3-kW level and succeeded in attaining an average power of 5.1 kW with CW operation and 3.3 kW with combined mode of CW and QCW operation. We also obtained electrical-optical efficiency of 22% in CW operation and that of 26% in QCW operation with average power of 2 kW.
