We demonstrate for the first time to our knowledge the use of

{Fe}_{3} O_{4}

nanoparticles for

Q

-switching a tunable mid-infrared (Mid-IR)

{Dy}^{3 +}

-doped ZBLAN fiber laser around 3 μm. The

Q

-switcher was fabricated by depositing the prepared

{Fe}_{3} O_{4}

nanoparticles solution onto an Au mirror. Its nonlinear optical response was characterized using a mode locked

{Ho}^{3 +} / \Pr^{3 +}

-codoped ZBLAN fiber laser at 2.87 μm, and showed a modulation depth of 11.9% as well as a saturation intensity of

1.44 MW / {cm}^{2}

. Inserting the device into a tunable

{Dy}^{3 +}

-doped ZBLAN fiber laser, stable

Q

-switched pulses within the tunable range of 2812.4–3031.6 nm were obtained. When tuning the wavelength to 2931.2 nm, a maximum

Q

-switching output power of 111.0 mW was achieved with a repetition rate of 123.0 kHz and a pulse width of 1.25 μs. The corresponding pulse energy was 0.90 μJ. This demonstration suggests that

{Fe}_{3} O_{4}

nanoparticles are a promising broadband saturable absorption material for mid-infrared operation.
