Abstract
The invention concerns a laser system with a frequency comb generator for generating a comb of optical frequencies having an offset frequency and a plurality of equidistant modes. The laser system further preferably includes at least one stabilizer for stabilizing the frequency comb onto a certain offset frequency and/or onto a certain mode spacing. The laser system further includes an optical amplifier for amplifying the frequency comb coupled out of the frequency comb generator, the amplification factor of this amplifier being variable; and the amplifier is followed by a Raman medium for generating a Raman shift of the frequency comb.
Claims35
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.
