C-Band Q-Switched Fiber Laser Using Titanium Dioxide (TiO 2) As Saturable Absorber

C-Band Q-Switched Fiber Laser Using Titanium Dioxide (TiO 2) As Saturable Absorber

We demonstrate a passively Q-switched erbium fiber laser using titanium dioxide (TiO2) as a saturable absorber. The TiO<sub>2</sub> saturable absorber was fabricated as a polymer composite film and sandwiched between fiber ferrules. Q-switched pulsing starts with the assistance of physic...
