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 started to generate at the threshold pump power of 24.13 mW with centre wavelength of 1558.7 nm. The Q-switched performances were achieved at the maximum pump power of 125.63 mW with a repetition rate of 109.2 kHz and a minimum pulse width of 2.89 mu s. The higher pulse energy obtained is 73.8 nJ, with a maximum average output power of 8.06 mW. Our findings suggest that In2Se3 has merciless performance in acting as passive saturable absorber in midinfrared regime and will provide useful guidance for future ultra-fast optical devices.
