Abstract

We present first to our knowledge self-starting graphene-chitosan based ultrafast fiber laser setup. Graphene-chitosan composite placed between two fibres connectors is saturable absorber in demonstrated setup and is responsible for modelocking operation. Laser is built with polarization maintaining fibres which grants self-start feature. Laser produces ~300 fs soliton pulses centered at 1566 nm with 10 nm FHWM optical bandwidth. Time bandwidth product of demonstrated laser is 0.37. Repetition rate of 42 MHz and average output power of 1.2 mw corresponds to pulse energy and peak power of 20 pJ and 62 W, respectively. As an active media in laser Erbium-doper fiber was used. Presented setup proves graphene is novel promising material for ultrafast lasers production at worldwide scale.
