Abstract

An enhancement resonator (20) being configured for generating intra-resonator laser light (1) by coherent superposition of input laser light, comprises at least three resonator mirrors (21, 22, 23, 24) spanning a ring resonator path in one common resonator plane, said resonator path being free of a laser light amplifying medium, wherein the at least three resonator mirrors (21, 22, 23, 24) include at least two toroidal mirrors and/or at least one cylindrical mirror. Furthermore, a laser device (100) comprising the enhancement resonator (20) and a method of generating intra-resonator laser light (1) are described.
