Graphene mode-lockers for fiber lasers functioned with evanescent field interaction

Graphene mode-lockers for fiber lasers functioned with evanescent
field interaction

Employing graphene as an intracavity passive power modulating element, we demonstrate the
efficient laser pulsation in high pulse-energy regime with evanescent field interaction between the
propagating light and graphene layer. Graphene is prepared by the solution based reduction of
graphene oxide, and dispersed homogeneously into the water for spray onto an all-fiber substrate,
side-polished fiber. With the intracavity power up to 21.41 dBm, we ensure the robust high-energy
operation without any thermal damage of graphene. Resultant output pulses have center wavelength,
spectral width, and repetition rate of 1561.6 nm, 1.96 nm, and 6.99 MHz, respectively.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at
