【 摘 要 】

This paper demonstrates a Q-switched Brillouin-Raman fiber laser (BRFL) operating at 1563nm. The BRFL uses a 7.7 km dispersion compensating fiber (DCF) as nonlinear gain medium and graphene as a saturable absorber. As the pump power is increased, the repetition rate increases from 20.80 kHz to 21.99 kHz while the pulse width decreased from 15.45 μs to 12.34 μs. The highest pulse energy is 1407.913 nJ. This result shows that the graphene SA has a high potential to be used for pulsed BRFL generation.
