Spatially relaying radiation components

摘要

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.
