The invention relates to a linear-resonator fiber laser, especially for generating self-similar pulses, comprising a pump source (6) and a linear resonator. The linear resonator is provided with two reflectors (1), a polarization-maintaining fiber (3) that is doped by means of an intensifying medium and has a normal dispersion ß2 > 0 in the frequency range predefined by the intensifying medium, a dispersion-compensating element (2) having an anomalous dispersion ß2 0. The fiber (3), the dispersion-compensating element (2), the element (8) for extracting radiation, and the non-linear mode-coupling element (1b, 1c) are disposed between the two reflectors (1) in a joint beam path defined by the resonators. The total dispersion of the components located in the beam path is normal.
