Copper oxide nanomaterial saturable absorber as a new passive Q-switcher in erbium-doped fiber laser ring cavity configuration

A passively Q-switched erbium-doped fiber laser (EDFL) operating at 1560 nm is demonstrated by using a copper oxide (CuO) film as a saturable absorber (SA). The SA was prepared by embedding CuO nanoparticles (NPs) into a polyvinyl alcohol (PVA) by solution casting method. The CuO-SA has a modulation...
