Abstract
AbstractErbium-doped fibre laser mode-locked by a graphene saturable absorber is presented. Pulses with 630-fs duration and 41.9-MHz repetition frequency were achieved at the centre wavelength of 1562 nm and 9-nm FWHM bandwidth. Multilayer graphene was obtained by mechanical exfoliation from a pure graphite block by using the scotch-tape method and deposited on a fibre ferrule to form a saturable absorber. The laser operated in a mode-locked regime with 37-mW pumping and 4-mW output power.
