Abstract We report the generation of mode-locked thulium-holmium doped fiber laser (THDFL) at 1979 nm. This is a first demonstration of mode-locked by using Titanium Dioxide (TiO 2 ) film as a saturable absorber (SA). A piece of 1 mm×1 mm TiO 2 film was sandwiched in between two fiber ferrule in the cavity. Fabrication process of TiO 2 film incorporated a TiO 2 and a polyvinyl alcohol (PVA). The stable 9 MHz repetition rate of mode-locked mode operation with 58 dB SNR was generated under pump power of 902–1062 mW. At maximum pump power, the mode-locked THDFL has output power and pulse energy of 15 mW and 1.66 nJ, respectively. Our results demonstrate the TiO 2 can be used promisingly in ultrafast photonics applications.
