Year: 2025

Type: article

Abstract: This study reports the generation of dissipative soliton resonance (DSR) mode-locked pulses in an erbium-ytterbium doped fiber laser using a hybrid configuration combining graphene oxide/zinc oxide (rGO/ZnO) nanocomposite on an arc-shaped fiber as a saturable absorber (SA) with a nonlinear amplified loop mirror (NALM). Implementing the hybrid configuration gave an output spectrum with center wavelength and signal-to-noise ratio (SNR) of 1564 nm and 55 dB respectively. The hybrid setup generates 80 ns pulses with a pulse energy of 99.51 nJ. The system is very stable over time. This study highlights the performance of hybrid configuration in enhancing the generation of DSR mode-locked pulses that could be useful for practical applications in optical technologies.
