Abstract

Abstract

Power scaling of high-brightness fiber laser is limited by the mode instability and nonlinear effects. To overcome these limiting factors, a large mode area confined-doped fiber is designed and fabricated. By utilizing the homemade confined-doped fiber and backward tandem pumping scheme, fiber laser with output power of 10.1 kW is successfully achieved, where the corresponding beam quality factor （M²） is 2.16.
- high power,
- fiber laser,
- confined-doped fiber,
- good beam quality
