摘要：
We demonstrate a high brightness, polarization maintaining 42+1 to 1 cascaded combiner system which consists of a tree architecture with one 6+1 to 1 pump-signal combiner pumped with six multimode pump combiners. The cascaded combiner system has a pump efficiency of 95%, high beam quality with greater than 20dB PER. In this work the higher brightness of the combiner system is driven by choice of optimized pump fibers and high efficiency of multimode pump combiners that operate at an average pump efficiency of 99%.
