Q switching was demonstrated in an Erbium-doped fiber laser by utilizing Indium Selenide (In2Se3)-PVA as a passive saturable absorber (SA). The In2Se3 PVA thin film was sandwiched between two fibre ferrules using 980 nm laser diode at the operating wavelength of 1550 nm. Stable Q-switched pulse star...
