论文摘要
我们提出了一个基于杆型，掺杂的，掺杂的，具有4x4核的多核纤维的连贯合并的飞秒纤维CPA系统。高平均功率高达500 W（组合和压缩后）可以以10 MHz的重复速率实现，并具有出色的梁质量。此外，使用此设置还实现了<500 fs脉冲，脉冲能量高达600 UJ。通过增加纤维中的核心数量，该体系结构在本质上可扩展。
We present a coherently-combined femtosecond fiber CPA system based on a rod-type, Ytterbium-doped, multicore fiber with 4x4 cores. A high average power of up to 500 W (after combination and compression) could be achieved at 10 MHz repetition rate with an excellent beam quality. Additionally, <500 fs pulses with up to 600 uJ of pulse energy were also realized with this setup. This architecture is intrinsically power scalable by increasing the number of cores in the fiber.
