We demonstrate a compact, all-fiber Q-switched hafnium bismuth erbium co-doped fiber laser based on bismuth-doped fiber (BDF) as the saturable absorber (SA). The laser cavity was constructed using a homemade hafnium bismuth erbium co-doped fiber as gain medium. It was found that stable Q-switched pu...
