چکیده
|
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. © 2016 penerbit utm press. all rights reserved.
