摘要
We report a nanosecond-pulse amplification system based on an Yb-doped, 100-μm core, rod-type photonic crystal fiber. Up to 10 W of average power with pulse energy of I mJ and peak power of 450 kW is obtained at the repetition rate of 10 kHz. The high-power nanosecond pulse has a good pulse shape and spectral characteristics. The usage of rod-type fibers provides a novel structure for nanosecond pulse amplification.
