商用 0.5 kW 掺镱光纤放大器已被表征并被发现适合相干光束组合。八个这样的光纤放大器以平铺孔径配置相干组合，组合效率为 78%，总输出功率为 4 kW。组合输出的桶内功率垂直光束质量是全功率时衍射极限的 1.25 倍。光束组合性能与输出功率无关。
Commercial 0.5 kW Yb-doped fiber amplifiers have been characterized and found to be suitable for coherent beam combining. Eight such fiber amplifiers have been coherently combined in a tiled-aperture configuration with 78% combining efficiency and total output power of 4 kW. The power-in-the-bucket vertical beam quality of the combined output is 1.25 times diffraction limited at full power. The beam-combining performance is independent of output power.
