The invention relates to a method for generating coherent-phase light having a predefinable frequency value (νSoll), comprising the steps of generating working light with a working frequency (νSL), 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 (νm), generating a frequency shift (Δν) of the frequency comb (10) and/or the working frequency (νSL) by means of time-dependent phase settings (φS(t)) modulo a multiple of 2π, in particular of 2π, and phase-coupling the possibly frequency-shifted fields of the working light (νSL) and the one possibly frequency-shifted frequency comb line (νm), so that the frequencies thereof are rigidly phase-coupled via the frequency shift (Δν), and working light having the desired frequency (νSoll) is obtained.
