Method for producing a laser device

A method for producing a laser device comprising:

• a semiconductor laser configured to emit a laser beam;
• and
• a lens position-adjusted relative to the semiconductor laser,
• wherein the lens is firstly shifted perpendicularly to the expansion direction of the laser beam and is consequently penetrated by the laser beam,
• wherein the optical axis of the lens lies parallel to the expansion direction of the laser beam, and the lens is then fastened to a lens holder by a joining connection by flowing material, which solidifies in order to form the joining connection, such that the mobility of the lens perpendicular to the expansion direction of the laser beam is blocked,
• wherein, following a movement of the lens perpendicular to and in the expansion direction, the lens holder is guided to the lens and is consequently connected thereto only by a guiding device used for assembly and which is removed once the joining connection is produced between the lens holder and the lens,
• wherein the semiconductor laser is mounted in a housing and the mobility of the lens in the expansion direction is blocked by a joining connection between housing and lens holder by flowing material, which solidifies to form the joining connection, and
• wherein the lens holder is a tubular body with a through-opening such that the lens holder can be pushed onto the housing and is pushed onto the housing before the lens is moved.
