Abstract
We demonstrated nanosecond pulsed fiber laser operating at 1563 nm by using a newly developed Bismuth (III) Telluride (Bi2Te3) based saturable absorber (SA). The SA was obtained by embedding Bi2Te3 material into polyvinyl Alcohol (PVA) film. By incorporating the SA into a 209 m long cavity Erbium-doped fiber laser (EDFL), a stable nanosecond pulses were generated. It operated at repetition rate of 1.8 MHz with a pulse width of 193 ns and a signal-to-noise ratio (SNR) of 58 dB. The newly developed Bi2Te3 SA has a potential to be further enhanced towards better generation of ultrashort pulse fiber lasers. © 2019, S.C. Virtual Company of Phisics S.R.L. All rights reserved.
