Abstract
An apparatus for the coupling of laser radiation into a microwave waveguide, in which the laser radiation and the microwave enter the waveguide perpendicular to one another and, after the microwave is deflected, exit the waveguide colinearly. To enlarge the cross section of the laser beam to be coupled and to be able to adjust it to the microwave waveguide, the invention provides that the entry aperture for the laser beam incorporates a corrugated bandstop filter, and that the entry aperture for the microwave is configured in the manner of an orthomode coupler.
