An actively Q‐switched diode‐pumped Ho 3 + , Pr 3 + ‐co‐doped fluoride glass fibre laser operating in the first‐order diffraction mode is demonstrated. At a repetition a rate of 1 kHz, the laser produces pulses with a maximum peak power of 576 W and a pulse width of 33 ns at an average power of 19 mW at 2.87 µm.
