摘要：
In this paper we present the performance characterization of Erbium-doped Fiber Pulsed (EDFL) laser with monolayer graphene as satuble absorber, when the Pulse Repetition Rate (PRR) and Spectral Width (SPW) are changed by introducing cavity dispersion variations by cavity length increases. For cavity lengths between 4.86 m and 24.86 m, the obtained PRR was between 8 MHz and 41 MHz, and the SPW changing between 18.40 nm and 2.08 nm. The SPW and the PRR performance showed a inversely proportional behaviour respect to cavity length L. For the case of the PRR, the fitting curve obtained was 200 L-1 with a Pearson correlation coefficient r=1.
