Abstract

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.

使用d型光纤/石墨烯饱和吸收材料的短EDFL腔的重复率和光谱性能
本文研究了以单层石墨烯为饱和吸收体的掺铒光纤脉冲(EDFL)激光器,当脉冲重复率(PRR)和光谱宽度(SPW)随腔长增加而改变时的性能特性。当腔长为4.86 ~ 24.86 m时,得到的PRR在8 ~ 41 MHz之间,SPW在18.40 ~ 2.08 nm之间变化。SPW和PRR性能与腔长L呈反比关系。对于PRR,拟合曲线为200 L−1,Pearson相关系数r=1。
