| Abstract: | High-power Yb-doped double-clad fiber lasers have incited particular interest as efficient, compact lasers with good beam quality for a variety of applications in industry processing, medical instruments and national defense.In this paper, the recent progress of CW and pulsed double-clad fiber lasers at SIOM are reported upon. A CW 440 W fiber laser is demonstrated with two ends pumping configuration by using a 15 m home-made double -clad Yb-doped fiber. For pulsed operation, a 133 W average-power output at 100 kHz repetition rate is obtained with 4 m double-clad fiber by using MOPA technology. |
