Mode-locked erbium-doped fiber laser employing cobalt doped zinc oxide saturable absorber

We demonstrated a passive mode-locked Erbium-doped fiber laser (EDFL) based on cobalt-doped zinc oxide (Co-ZnO) nanorods saturable absorber (SA). The nanorods were embedded into a polyvinyl alcohol (PVA) film as a passive mode-locker. The SA was fabricated by mixing nanorods Co-ZnO solution with PVA...
