Graphene Q-switched, tunable fiber laser

Published 31 Oct 2010 in cond-mat.mes-hall and cond-mat.mtrl-sci | (1011.0115v1)

Abstract: We demonstrate a wideband-tunable Q-switched fiber laser exploiting a graphene saturable absorber. We get ~2us pulses, tunable between 1522 and 1555nm with up to~40nJ energy. This is a simple and low-cost light source for metrology, environmental sensing and biomedical diagnostics.
