  • Method for producing a radiation-emitting component, and radiation-emitting component
    Patent number: 11686999
    Abstract: The invention relates a method for producing a radiation-emitting component including a step A, in which a laser having an optical resonator and an output mirror is provided, wherein during the intended operation, laser radiation exits the optical resonator via the output mirror. In a step B), a photoresist layer is applied to the output mirror. In a step C), an optical structure is generated from the photoresist layer by means of a 3D lithography method, wherein the optical structure is designed to influence the beam path of the laser radiation by refraction and/or reflection.
