METHOD FOR GENERATING PHASE-COHERENT LIGHT FIELDS HAVING A PREDETERMINED FREQUENCY AND OPTICAL FREQUENCY SYNTHESIZER

摘要

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