Abstract (en)
[origin: WO2016134853A1] The invention relates to a method for operating a laser device (1), by means of which an optical frequency comb can be stabilized, wherein the frequencies of the modes thereof are describable by the formula fm= m x frep + f0, where frep is a mode spacing, f0 is an offset frequency and m is a natural number. At least one signal (S1, S2, S3, S4) is determined, which correlates with an actual value of a degree of freedom (F), wherein the degree of freedom (F) is a linear combination of the offset frequency f0 and the mode spacing frep of the frequency comb. The actual value of the degree of freedom (F) is set in a predetermined capture range (F) of a second control unit (40) using a first control unit (10) on the basis of the signal. As soon as the capture range (ΔFcapture) of the second control unit (40) is reached, the second control unit (40) is activated and the actual value is regulated to an intended value (Fintended) with the aid of the second control unit (40).
