This paper presents the high signal-to-noise ratio (SNR) Q-switched erbium-doped fiber laser pulse emission using a commercial single layer graphene (SLG) film as a saturable absorber (SA). A sandwiched-type structure with transferred single layer SLG film between two fiber ferrules is formed to function as the SA. Q-switched pulse emission with repetition rate from 47.25 kHz to 67.39 kHz and round-trip time per oscillation from 7.42 µs to 10.36 µs are obtained from the laser cavity set-up. The SNR of 62.64 dB shows a good quality of pulse generation using the SLG film as SA. The effortless production of SLG is enabling factor to produce fast fabrication and low cost SA for application in Q-switched pulsed fiber lasers.

<span lang="EN-US">In this paper, we demonstrated a Q-switched erbium doped fiber laser (EDFL) incorporating Antimony (III) Telluride (Sb<sub>2</sub>Te<sub>3</sub>) in polyvinyl alchohol (PVA) as passive saturable absorber.  The saturable absorber were fabricated by dissolving Antimony (III) Telluride powder into PVA solution and dry in the ambient temperature for 48 hours. Then, 1 mm<sup>2</sup> x 1 mm<sup>2</sup> Sb<sub>2</sub>Te<sub>3</sub>-PVA film based saturable absorber were sandwiched in between FC/PC ferrule for Q-switched laser generation. The stable and self-started Q-switched laser operates at center wavelength 1560 nm with 3 dB bandwidth of 0.23 nm. The laser operates at pump power of 29.3 mW until 84.9 mW with repetition rate of 20.99 kHz to 89.29 kHz and pulse width of 13.95 µs to 5.10 µs. At maximum pump power, the laser able to achieve pulse energy of 62.72 nJ and high signal to noise ratio of 71.4</span>

A tunable and switchable erbium-doped fiber (EDF) laser based on modal interference has been proposed and experimentally demonstrated in this paper. Here a core-offset structure has been used to excite the cladding modes and a segment of polarization maintaining fiber inserted in a Sagnac loop interferometer has been used as wavelength selective component. By adjusting the statement of polarization controller (PC) and the bending of the core-offset structure, a tunable and switchable fiber laser with the signal-to-noise ratio (SNR) of more than 50 dB has been achieved in this paper.
