Four actively phase-locked beams produced by fiber amplifiers in a master oscillator power amplifier (MOPA) configuration were coherently combined in a glass capillary re-imaging waveguide producing more than 100 W of coherent output with 80% combining efficiency and excellent beam quality. The beam combiner components maintained a temperature below 30 degrees C with no external cooling at >100 W of combined power.
由主振荡功率放大器（MOPA）配置中的光纤放大器产生的四个处于主动锁相状态的光束，在玻璃毛细管再成像波导中进行了相干合成，产生了超过100瓦的相干输出，合成效率达80%，且光束质量优异。在合成功率大于100瓦的情况下，光束合成器组件在无需外部冷却的情况下保持温度低于30摄氏度。
