Abstract
The invention relates to a method for producing a semiconductor laser comprising the method steps: generating a lateral structure layer, at least in the material abrasion areas, a basic selection of the laser modes amplified or amplifiable through stimulated emission taking place via the lateral structure layer; and generating an optical element for defining the phasing of the amplified or amplifiable laser modes, the optical element being generated in such a manner that it has a distance d to an end of the lateral structure layer in the longitudinal direction of the waveguide ridge, distance d fulfilling the condition m being a natural number (m∈) and λbeing the effective wavelength in the material.
