Development of q-switched and modelocked erbium-doped fiber lasers (EDFL) based on gold nanoparticles (GNP) as saturable absorber / Nursyazana Zainal Abidin

In this experiment, we experimentally demonstrate a Q-switched and mode-locked Erbium-doped fiber lasers (EDFLs) using gold nanoparticle (GNPs) which is embedded into a polyvinyl alcohol (PVA) film as a passive saturable absorber (SA). The film is sandwiched between two ferrules via a fiber connecto...
