A method of spatially relaying a first radiation component ( 1 ) having a first wavelength and a second radiation component ( 2 ) having a second wavelength different from the first radiation component ( 1 ), using an optical relaying device ( 10 ) which comprises a transparent plate ( 11 ) having anti-reflection coatings ( 12, 13 ) on both side surfaces thereof, comprises transmitting the first radiation component ( 1 ) across the optical relaying device ( 10 ) with predetermined incident (a) and emergent angles (β), resp., wherein said anti-reflection coatings ( 12, 13 ) being effective for the first radiation component ( 1 ) at the incident and emergent angles (α, β), resp., and reflecting the second radiation component ( 2 ) at the optical relaying device ( 10 ) with a predetermined reflection angle (a) being equal to at least one of said incident and emergent angles (α, β), wherein the first and second radiation components ( 1, 2 ) are split from each other toward different directions or combined into a common beam path. Furthermore, an optical relaying device ( 10 ) and a resonator device, in particular enhancement cavity device ( 100 ) and a laser resonator, are described. |
