We have designed and built a chirped-pulse parametric-amplifier system that utilizes a 10 Hz, 300 ps, Nd:YAG pump laser system; a 1.575 microm fiber oscillator and amplifier as the signal source; and rubidium titanyl phosphate and potassium titanyl arsenate nonlinear crystals. We obtained 260 fs, 30 mJ pulses centered at 1.550 microm, representing a gain of > 10(9) and a peak power of 100 GW. To our knowledge, these are the highest energy and peak power pulses ever produced in the 1.5-2.0 microm region
我们设计并构建了一个啁啾脉冲参量放大器系统，该系统利用了一个10赫兹、300皮秒的钕:钇铝石榴石泵浦激光系统；一个1.575微米的光纤振荡器和放大器作为信号源；以及磷酸钛氧铷和砷酸钛氧钾非线性晶体。我们获得了中心波长为1.550微米、脉宽为260飞秒、能量为30毫焦的脉冲，增益大于10^9，峰值功率为100吉瓦。据我们所知，这些是1.5 - 2.0微米波段产生的最高能量和峰值功率的脉冲。
