Alq 3 saturable absorber for generating Q‐switched pulses in erbium‐doped fiber laser

Q-switch pulses were successfully produced utilizing an organic saturable absorber (SA) to modulate loss inside an erbium-doped fiber laser (EDFL) cavity. The organic material was tris-(8-hydroxyquinoline) aluminum (Alq3) and it was mixed with polyvinyl alcohol to form a film. The Q-switched EDFL op...
