Abstract: The invention relates to a method for generating coherent-phase light having a predefinable frequency value (?Soll), comprising the steps of generating working light with a working frequency (?SL), generating a frequency comb (10), which is a light field that consists of equidistant coherent-phase spectral lines, selecting a comb line (having the index m) from the frequency comb (10) having a frequency (?m), generating a frequency shift (??) of the frequency comb (10) and/or the working frequency (?SL) by means of time-dependent phase settings (?S(t)) modulo a multiple of 2?, in particular of 2?, and phase-coupling the possibly frequency-shifted fields of the working light (?SL) and the one possibly frequency-shifted frequency comb line (?m), so that the frequencies thereof are rigidly phase-coupled via the frequency shift (??), and working light having the desired frequency (?Soll) is obtained.
