Pulsed laser performance of erbium doped fiber laser using titanium dioxide nanoparticles as saturable absorber
In this work, titanium dioxide TiO2 nanoparticles embedded in thin composite film was used as saturable absorber (SA) in erbium doped fiber (EDF) laser. The thin film was prepared by mixing TiO2 nanoparticles with polyvinyl alcohol (PVA) as host. Upon inserting the SA in a laser cavity, the output s...
