Abstract

We present a coherently combined laser amplifier with 16 channels from a multicore fiber in a proof-of-principle demonstration. Filled-aperture beam splitting and combination, together with temporal phasing, is realized in a compact and low-component-count setup. Combined average power of up to 70 W with 40 ps pulses is achieved with combination efficiencies around 80%.

摘要

在原理验证演示中，我们展示了一种来自多芯光纤的具有16个通道的相干合成激光放大器。在一个紧凑且元件数量少的装置中实现了填充孔径光束的分束与合成以及时间相位调整。通过约80%的合成效率，实现了高达70W的40ps脉冲的合成平均功率。
