The invention relates to a method for generating coherent-phase light having a predefinable frequency value (&#x3bd;), comprising the steps of generating working light with a working frequency (&#x3bd;), generating a frequency comb (), 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 () having a frequency (&#x3bd;), generating a frequency shift (&#x394;&#x3bd;) of the frequency comb () and/or the working frequency (&#x3bd;) by means of time-dependent phase settings (&#x3c6;(t)) modulo a multiple of 2&#x3c0;, in particular of 2&#x3c0;, and phase-coupling the possibly frequency-shifted fields of the working light (&#x3bd;) and the one possibly frequency-shifted frequency comb line (&#x3bd;), so that the frequencies thereof are rigidly phase-coupled via the frequency shift (&#x394;&#x3bd;), and working light having the desired frequency (&#x3bd;) is obtained.
