Abstract

In this paper we present a dual-wavelength fiber mode-locked laser based on CVD-graphene saturable absorber (SA). The laser setup is based on two ring cavities connected by a common branch with a graphene SA. As a gain media erbium (Er) and thulium (Tm) doped active fiber were used. The laser generate optical pulses centered at 1558.5 nm and 1937 nm. The repetition rates and pulse durations were of 23.2 MHz, 16.42 MHz and 0.95 ps, 1.03 ps for the solitons generated in Er- and Tm-doped cavities, respectively.
