Fiber lasers operating in the soliton regime are limited in terms of the available peak powers and pulse durations by fiber nonlinearities that rise when ultra-short pulses with large pulse energies propagate through the fiber. In order to alleviate this limitation, researchers are focusing on alternative modelocking regimes such as the stretched-pulse evolution to reach higher pulse energies and shorter pulse durations. Here, we demonstrate stretched-pulse modelocking using a saturable absorber fabricated by mechanical exfoliation of graphene. Such saturable absorber offers advantages such as ease of fabrication and robustness to optical damage under high intensities. |
