Abstract

We experimentally demonstrate a passively Q-switched erbium-doped fiber laser (EDFL) operation by using a saturable absorber (SA) based on tungsten disulfide (WS2). By depositing WS2 thin film layer at the end of optical fiber ferrule, we fabricated a SA device. The SA is incorporated into an Erbium-doped fiber laser (EDFL) cavity to generate a Q-switching pulses train operating at 1559.8 nm. As a result, stable passively Q-switched EDFL pulses with maximum output pulse energy of 123.2 nJ, repetition rate of 104.1 kHz, and pulse width of 9.61 us are achieved when the input pump power is 142.1 mW at the wavelength of 980 nm.
