High power fiber lasers

摘要

High power fiber lasers are one of the hot topics in the laser science and technology recent year. The clad pumping of double clad fiber lasers was the key issue for high power performance last decade. The clad pumping scheme demonstrated more than 100W from a single core fiber. A new concept of high power fiber lasers, a fiber disk laser, was developed in Japan in she middle of 90th. The fabrication technique of fiber embedded disk was developed in the cooperation program supported by Japanese government. We report she concept of high power fiber lasers under development in Japan.
