We successfully demonstrate a Q-switched erbium-doped fiber laser (EDFL) using titanium dioxide (TiO2) coated onto a fiber ferrule as a saturable absorber (SA). The fiber ferrule is immersed into a TiO2 colloid, using the dip-coating method to prepare the SA. Stable pulses operating at 1,565 nm with a 3 dB bandwidth of 1.9 nm are achieved within the pump power range from 63.41 to 104.62 mW. A maximum repetition rate of 72.89 kHz and a pulse energy of 29.91 nJ are respectively generated, while the minimum pulse width is 3.02 mu s. To the best of our knowledge, this is the first demonstration of EDFL passive Q-switching using TiO2 colloid.
