Abstract
A laser component has a housing, which includes a carrier having a cavity with a bottom surface and a sidewall, wherein the cavity widens starting from the bottom surface, the side wall is inclined relative to the bottom surface by an angle different from 45°, a laser chip, an emission direction of which is oriented parallel to the bottom surface, is arranged on the bottom surface in the cavity, a reflective element is arranged in the cavity and bears on an edge between the bottom surface and the side wall, a reflective surface of the reflective element defines an angle with the bottom surface of the cavity, and the emission direction defines an angle of 45° with the reflective surface of the reflective element.

A laser component having a housing, which comprises a carrier having a cavity with a bottom surface and a side wall,
- wherein the cavity widens starting from the bottom surface,
- the side wall is inclined relative to the bottom surface by an angle different from 45°,
- a laser chip, an emission direction of which is oriented parallel to the bottom surface, is arranged on the bottom surface in the cavity,
- a reflective element is arranged and fastened in the cavity by a solder connection or an adhesive bond and bears on an edge between the bottom surface and the side wall,
- a reflective surface of the reflective element defines an angle of 45° with the bottom surface of the cavity, and
- the emission direction defines an angle of 45° with the reflective surface of the reflective element.
A method of producing a laser component comprising:
- providing a carrier having a cavity with a bottom surface and a side wall, the cavity widening starting from the bottom surface, wherein the side wall is inclined relative to the bottom surface by an angle different from 45°;
- arranging a laser chip on the bottom surface in the cavity such that an emission direction of the laser chip is oriented parallel to the bottom surface;
- and
- arranging a reflective element in the cavity and fastening the reflective element in the cavity by a solder connection or an adhesive bond such that the reflective element bears on an edge between the bottom surface and the side wall, a reflective surface of the reflective element defines an angle of 45° with the bottom surface of the cavity, and the emission direction defines an angle of 45° with the reflective surface of the reflective element.
