An ultrafast fiber-chirped-pulse amplification system using a combination of spatial and temporal coherent pulse combination is presented. By distributing the amplification among eight amplifier channels and four pulse replicas, up to 12 mJ pulse energy with 700 W average power and 262 fs pulse duration have been obtained with a system efficiency of 78% and excellent beam quality. To the best of our knowledge, this is the highest energy achieved by an ultrafast fiber-based laser system to date.
介绍了一种采用空间和时间相干脉冲组合的超快光纤啁啾脉冲放大系统。通过在八个放大器通道和四个脉冲复制品之间分配放大，获得了高达12 mJ的脉冲能量、700 W的平均功率和262 fs的脉冲持续时间，系统效率为78%，光束质量优异。据我们所知，这是迄今为止超快光纤激光系统所实现的最高能量。
