Passively Q-switched 2?m fiber laser with WO3 saturable absorber

We have successfully demonstrated a reliable and simple passively Q-switched Thulium-doped fiber laser (TDFL) utilizing tungsten oxide (WO3) as a saturable absorber (SA). The SA film was fabricated by embedding WO3 material into Polyvinyl alcohol (PVA) host polymer. The saturable absorption and satu...
