We report the demonstration of a 2850 nm diode-pumped Ho, Pr co-doped fluoride fiber amplifier that delivers pulses with an average power of 2.45 W, 122 μJ energy, and 500 ps duration at a repetition rate of 20 kHz. To the best of our knowledge, the average power and pulse energy are the highest to be obtained from a sub-nanosecond fiber source operating in the 3 μm spectral region. The amplifier is seeded by an optical parametric generation source and is pumped around 915 nm using widely available InGaAs laser diodes.
我们展示了一种 2850nm 二极管泵浦 Ho、Pr 共掺氟化物光纤放大器的演示，该放大器以 20kHz 的重复率输出平均功率为 2.45W、122μJ 能量和 500ps 持续时间的脉冲。据我们所知，这是在 3μm 光谱区域工作的亚纳秒光纤源获得的最高平均功率和脉冲能量。该放大器由光参量产生源种子，并使用广泛可用的 InGaAs 激光二极管在 915nm 左右泵浦。
