We report on the experimental demonstration of a fiber chirped- pulse amplification system capable of generating nearly transform-limited sub 500 fs pulses with 2.2 mJ pulse energy at 11 W average power. The resulting record peak power of 3.8 GW could be achieved by combining active phase shaping with an efficient reduction of the acquired nonlinear phase. Therefore, we used an Ytterbium-doped large-pitch fiber with a mode field diameter of 105 µm as the main amplifier.
我们报道了一种光纤啁啾脉冲放大系统的实验演示，该系统能够产生近变换极限的亚500飞秒脉冲，脉冲能量为2.2毫焦，平均功率为11瓦。通过将有源相位整形与有效降低所获得的非线性相位相结合，可实现高达3.8吉瓦的创纪录峰值功率。因此，我们使用了模场直径为105微米的掺镱大节距光纤作为主放大器。
