A stable, power scaling, graphene-mode-locked all-fiber oscillator

We report power tunability in a fiber laser mode-locked with a solution-processed filtered graphene film on a fiber connector. similar to 370 fs pulses are generated with output power continuously tunable from similar to 4 up to similar to 52mW. This is a simple, low-cost, compact, portable, all-fiber ultrafast source for applications requiring environmentally stable, portable sources, such as imaging. Published by AIP Publishing.
