摘要：

We report the demonstration of a 2850 nm diode-pumped Ho3+, Pr3+ co-doped fluoride fiber amplifier that delivers pulses with an average power of 2.45 W, 122 mu J 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 mu m spectral region. The amplifier is seeded by an optical parametric generation source and is pumped around 915 nm using widely available InGaAs laser diodes. (C) 2018 Optical Society of America
