Abstract
In a device for optical coupling of a solid-state laser to an optical fiber, an anamorphic lens system is arranged between the output face of the solid-state laser and the input face of the optical fiber, the lens system converting differing apertures in the main sections of the solid-state laser into essentially identical apertures at the input face of the optical fiber. The lens system is composed of one anamorphic lens applied on the output face and a further lens applied on the input face.
