Deposition of silver nanoparticles on polyvinyl alcohol film using electron beam evaporation and its application as a passive saturable absorber

This study investigated the generation of Q-switched pulse in fibre laser operation at 1550 nm wavelength region using silver nanoparticles (Ag NPs) as passive saturable absorber (SA). The Ag NP SA was prepared through the electron beam evaporation method with a thickness of 10 nm on pure polyvinyl...
