23 mJ high-power fiber CPA system using electro-optically controlled divided-pulse amplification
摘要：
在基于相干组束的高功率超快光纤激光器系统中实现了脉冲能量定标技术电光控制分光脉冲放大。集成光纤的前端和基于多通池的后端实现了小尺寸和模块化实施。8个脉冲的突发在多达12个掺镱大间距光纤放大器中并行放大。随后将96个总的放大脉冲副本的时空相干组合成单个脉冲，导致在674 W的平均功率下的23 mJ的脉冲能量，可压缩到235 fs的脉冲持续时间。据我们所知，这是光纤CPA系统实现的最高脉冲能量。
英文摘要：
The pulse-energy scaling technique electro-optically controlled divided-pulse amplification is implemented in a high-power ultrafast fiber laser system based on coherent beam combination. A fiber-integrated front end and a multi-pass cell based back end allow for a small footprint and a modular implementation. Bursts of 8 pulses are amplified parallel in up to 12 ytterbium-doped large-pitch fiber amplifiers. Subsequent spatio-temporal coherent combination of the 96 total amplified pulse replicas to a single pulse results in a pulse energy of 23 mJ at an average power of 674 W, compressible to a pulse duration of 235 fs. To the best of our knowledge, this is the highest pulse energy ever accomplished with a fiber CPA system.
