Claim:
1. An optical resonator arrangement comprising a resonator and an interferometer having at least a first and a second interferometer leg arranged within the resonator, the first interferometer leg has a first optical path length and the second interferometer leg has a second optical path length other than the first optical path length, and a splitting ratio, with which the interferometer splits radiation circulating in the resonator into the first and second interferometer legs, is variably adjustable, wherein the resonator arrangement is configured to change a repetition rate of the resonator and a carrier envelope offset frequency by changing the splitting ratio of the radiation circulating in the resonator into the first and second interferometer legs, such that in a frequency domain, a comb of frequencies of the radiation circulating in the resonator contracts or expands by a uniform factor about a fixed point.
