Abstract

A diode-pumped mode-locked double clad Yb3+-fiber ring laser with up to 118 nm bandwidth, a repetition rate of 7.6 MHz and a maximum output power of 2.8 W is presented. The broad bandwidth is achieved by suppressing the long wavelength components in the dispersive grating line of the resonator.
