We have successfully demonstrated Q-switching within the confines of an erbium-doped fiber laser (EDFL) cavity. This innovative approach leveraged copper phthalocyanines (CuPc) as a saturable absorber (SA), with the SA film made via the embedding method utilizing polyvinyl alcohol (PVA). The Q-switc...
