Abstract

A fiber laser device comprises a ring shaped resonator (1) to generate pulses in a mode-locked regime, the ring shaped resonator (1) comprising a doped fiber (10), a virtual saturable absorber (11) receiving the output of the doped fiber (10), a standard fiber (12) connected to the virtual saturable absorber (11) and connected in loop to the doped fiber (10), the resonator (1) including an isolator (16) for unidirectional laser propagation from the doped fiber (10) to the saturable absorber (11), the virtual saturable absorber (11) comprising a splitter (115) to output a part of the light as main output, The doped fiber (10) is selected to operates in a regime where the group-velocity dispersion is negative within the selected band, the splitter (115) outputting more than 85% of the light power from the resonator (1), the resonator (1) comprising filtering means (17) selecting a band of light coupled to the standard fiber (12). Method of controlling such a device.
