Abstract
We report the generation of mode-locked thulium-holmium doped fiber laser (THDFL) at 1979Â nm. This is a first demonstration of mode-locked by using Titanium Dioxide (TiO2) film as a saturable absorber (SA). A piece of 1Â mmÃ1Â mm TiO2 film was sandwiched in between two fiber ferrule in the cavity. Fabrication process of TiO2 film incorporated a TiO2 and a polyvinyl alcohol (PVA). The stable 9Â MHz repetition rate of mode-locked mode operation with 58Â dB SNR was generated under pump power of 902-1062Â mW. At maximum pump power, the mode-locked THDFL has output power and pulse energy of 15Â mW and 1.66Â nJ, respectively. Our results demonstrate the TiO2 can be used promisingly in ultrafast photonics applications.
