A method of generating intra-resonator laser light () comprises the steps of coupling input laser light (), e. g. laser pulse or continuous-wave light, into an enhancement resonator (), which comprises at least two curved resonator mirrors () and which is free of a laser light amplifying medium, said at least two curved resonator mirrors () being consecutively arranged and spanning at least one resonator path with a predetermined resonator length (Lres), wherein said at least two curved resonator mirrors () providing at least two pairs of consecutive curved resonator mirrors which are serially coupled along said at least one resonator path, and coherent addition of the input laser light () in the enhancement resonator so that the intra-resonator laser light () is formed, wherein said at least two pairs of consecutive curved resonator mirrors each have a detuned concentric configuration, which deviates from a concentric configuration with regard to at least one of a distance between the curved mirrors. and an angle of incidence on the curved mirror surfaces. Furthermore, an enhancement resonator (), in particular being configured for generating intra-resonator laser light (), a laser device () including the enhancement resonator device () and applications of the enhancement resonator device () are described.
