TY - JOUR AB - We present results of high average power mid-infrared (mid-IR) generation employingsynchronized nanosecond pulsed ytterbium and erbium fiber amplifier systems using periodicallypoled lithium niobate. We generate greater than 6 W of mid-IR radiation tunable in wavelengthbetween 3.31–3.48μm, at power conversion efficiencies exceeding 75%, with near diffractionlimited beam quality (M2= 1.4). Numerical modeling is used to verify the experimental resultsin differing pump depletion regimes.
