【摘要】 |
|
Research on fiber laser combination is discussed briefly in this paper. High-power double clad-fiber laser beam combination technology is introduced and different kinds of fiber laser beam combination and coherent combination technologies are evaluated. Tapered fused bundle (TFB) couplers are used in laser combine for higher power. In this paper, the theory and progress in TFB coupling are introduced. The experiment on our self-fabricated TFB is presented. The efficiency of the fiber coupler exceeded 70% and increased as the input power went up. A maximum total output power of 689 W was obtained, with an efficiency of 74%. The fiber coupler displayed stability during the course of the experiment, without any cooling provided. |
