Broadband Tunable Passively Q-Switched Erbium-Doped ZBLAN Fiber Laser Using Fe<sub>3</sub>O<sub>4</sub>-Nanoparticle Saturable Absorber

We experimentally demonstrate a passively Q-switched wavelength tunable 2.8 μm erbium-doped fiber laser. Fe<sub>3</sub>O<sub>4</sub> nanoparticles deposited on a gold mirror are used as a saturable absorber (SA). Stable Q-switched pulses within the tunable range of 2710–2810...
