A fiber laser for the production of self-similar pulses contains a pumped source and a linear resonator. The linear resonator has two reflectors. The laser further includes a polarization-maintaining fiber doped with an amplifying medium with a normal dispersion β2>0 in the frequency range prescribed by the amplifying medium and a dispersion-compensating element with an anomalous dispersion β2<0. The laser further includes an element for decoupling radiation and a non-linear mode coupling element with a modulation depth >0. The fiber, dispersion-compensating element, element for decoupling radiation and non-linear mode coupling element are disposed between the two reflectors in a common beam path delimited by the resonators. The total dispersion of the components disposed in the beam path of the resonator is normal.
