Abstract: A laser device comprises a carrier, an optoelectronic component provided on the carrier, said component being designed to emit laser radiation, and an optical element designed to form the laser radiation emitted by the optoelectronic component, wherein: the optical element has a first layer that is at least partially transparent to the laser radiation, with a first refractive index, and a second layer that is at least partially transparent to the laser radiation, with a second refractive index; the first layer being applied to the optoelectronic component and having a surface with an imprinted structure; and the second layer is applied to the first layer, on the surface (24) having the imprinted structure.
