We demonstrate a passively Q-switched erbium-doped fiber laser using a tin(IV) oxide (SnO 2 ) nanoparticle layer as a saturable absorber. A SnO 2 nanoparticle is composited with polyvinyl alcohol (PVA) to form thin saturable absorber film and is sandwiched between fiber ferrules in a ring fiber lase...
