We have experimentally demonstrated a Q-switched fiber laser operating in the 1 µm region by using tris-(8-hydroxyquinoline) aluminum (Alq_3) as a saturable absorber (SA). The Alq_3 was fabricated through a drop-casting technique, where the material was embedded into a polyvinyl alcohol (PVA) film so that it can effectively incorporated into a laser cavity. The fiber laser has produced a high pulse energy of 0.8 µJ and peak power of 90 mW. When the laser cavity was reduced from 25 m to 5 m, the peak power increased and the pulse energy dropped to 237.62 mW and 451.5 nJ, respectively. Additionally, the minimum pulse width was reduced from 9 µs to 1.9 µs.
