1. A laser system comprising:

  • a frequency comb generator for generating a frequency comb of optical frequencies with an offset frequency and a plurality of equidistant modes;

    an optical amplifier for amplifying the frequency comb coupled out of the frequency comb generator;

    a Raman medium provided after the amplifier and adapted for generating a Raman shift of the frequency comb, the Raman medium being configured such that a soliton is generated from the frequency comb and a soliton self-frequency shift in the Raman medium leads to a frequency shift of the soliton; and

    a frequency dependent attenuator arranged downstream of the Raman medium, an attenuation degree of the attenuator being configured such that a constant mean laser power is provided behind the attenuator irrespective of the degree of the Raman shift,wherein an amplification factor of the amplifier is variable.
