We demonstrate the generation of Q-switched pulse train in Ytterbium-Doped Fiber Laser (YDFL) cavity by employing titanium (Ti) thin film as a passive saturable absorber (SA). The Ti-SA was fabricated by depositing Ti particles using electron beam evaporation on the surface of a polyvinyl alcohol (P...
