We use seven-core Yb-doped large-mode-area (LMA) photonic crystal fiber (PCF) to demonstrate phase-locked amplification of 0.7 W, 1 MHz, 1.9 ps laser pulses delivered by an LMA-PCF-laser-LMA-PCF-preamplifier system. Compression of the 24 W output of the multicore LMA-PCF amplifier with a grating compressor yields 110 fs pulses with a peak power up to 150 MW.
我们使用七芯掺镱大模场（LMA）光子晶体光纤（PCF），演示了由 LMA-PCF-激光器-LMA-PCF-预放大器系统传输的 0.7 W、1 MHz、1.9 ps 激光脉冲的锁相放大。使用光栅压缩器对多芯 LMA-PCF 放大器的 24 W 输出进行压缩，得到了 110 fs 脉冲，峰值功率高达 150 MW。
