我们目前的结果高平均功率中红外（中红外）产生同步纳秒脉冲镱和铒光纤放大器系统使用周期性极化的锂离子电池。我们产生了大于6 W的中红外辐射，波长在3.31-3.48 μm之间可调，功率转换效率超过75%，具有接近衍射极限的光束质量（M2 = 1.4）。数值模拟被用来验证实验结果在不同的泵浦耗尽制度。
We present results of high average power mid-infrared (mid-IR) generation employing synchronized nanosecond pulsed ytterbium and erbium fiber amplifier systems using periodically poled lithium niobate. We generate greater than 6 W of mid-IR radiation tunable in wavelength between 3.31-3.48 μm, at power conversion efficiencies exceeding 75%, with near diffraction limited beam quality (M2 = 1.4). Numerical modeling is used to verify the experimental results in differing pump depletion regimes.
