We report a passively Q-switched Erbium-doped fiber laser (EDFL) at 1566.96 nm by applying a new type of organic material based on turmeric as the saturable absorber (SA). The material was prepared by the embedding turmeric powder into polyvinyl alcohol (PVA) film. The prepared thin film was inserte...
