Passive Q-switching in an erbium-doped fiber laser using tungsten sulphoselenide as a saturable absorber

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.

Abstract – We demonstrate a Q-switched Erbium-doped fiber laser (EDFL) using a newly developed Graphene Oxide (GO) based saturable absorber (SA). The SA was fabricated by embedding a GO material, which was obtained through chemical oxidation of graphite into polyvinyl alcohol (PVA) film. A small piece of the film was sandwiched between two fiber ferrules via a fiber adapter and incorporated in an EDFL cavity for generating a stable Q-switching pulse train. The EDFL operates at 1560.5 nm with a pump power threshold of 16.88 mW while a pulse repetition rate was tunable from 32.45 to 81.7 kHz, and the smallest pulse-width of 5.67 μs. The Q-switching pulse shows no spectral modulation with a peak-to-pedestal ratio of 61.76 dB indicating the high stability of the laser. These results show that the GO has a great potential to be used for pulsed laser applications.Key words: graphene oxide, passive saturable absorber, Q-switching, EDFL, GO

Layered Transition Metal

A saturable absorber (SA) based on niobium diselenide (NbSe2), which is a layered transition metal dichalcogenide (TMD) in the VB group, is fabricated by the optically driven deposition method, and the related nonlinear optical properties are characterized. The modulation depth, saturable intensity, and nonsaturable loss of the as-prepared NbSe2 nanosheet-based SA are measured to be 16.2%, 0.76 MW/cm2, and 14%, respectively. By using the as-fabricated NbSe2 SA, a highly stable, passively Q-switched, erbium-doped, all-fiber laser is realized. The obtained shortest pulse width is 1.49 μs, with a pulse energy of 48.33 nJ at a center wavelength of 1560.38 nm. As far as we know, this is the shortest pulse duration ever obtained by an NbSe2 SA in a Q-switched fiber laser.
