Paper Abstract

We demonstrate a monolayer graphene based passively Q-switched fiber laser with cascaded amplifiers that can deliver 84.1 W average power at 1064 nm, with pulse energy of 1.67 mJ. To the best of our knowledge, this is the first time for a high power passively Q-switched fiber laser in the 1 μm range reported so far. More importantly, the Q-switched fiber laser operates stably during a week few-hours-per-a-day tests, which proves the stability and practical application value of graphene in high power pulsed fiber lasers.
