摘要

研究了准连续波工作中四个高亮度锥形放大器的相干光束组合。最大组合功率为22.7 W，组合效率> 64%。由于叠加的固有清理，组合输出的光束质量相对于单个放大器有所增加，从而产生衍射限制功率\gt 20w。

Coherent beam combining of tapered amplifiers under QCW regime

We demonstrate the coherent beam combining of four high-brightness tapered amplifiers in quasi continuous wave operation. A maximum combined power of 22.7 W was achieved with > 64 % combining efficiency. The beam quality of the combined output was increased with regard to the individual amplifiers thanks to the inherent clean-up of the superposition, resulting in a diffraction-limited power \gt 20 W.
