The utility model relates to laser technology, in particular to fiber lasers with normal dispersion resonator. This invention provides improved circuit lasers similaritonnogo type with width generation line, exceeding the width of the spectrum of amplification in active fiber. FIELD in resonator compression element with abnormal dispersion group velocities allows locally to increase peak power pulse and, respectively, to increase the width of the spectrum of generated pulse at its distribution in fiber - modulator. As a result, output impulse laser - wide range of as compared with the known version, and its compression may be conducted with more high quality.
