The present invention relates to laser diodes with single mode emission at high output powers, as well as to structures and processes facilitating simple manufacture of such a devices. The invention includes a semiconductor laser () with a semiconductor substrate (), a laser layer () arranged on the semiconductor substrate, an array of waveguide ridges () arranged at a distance from the laser layer, and several strip-shaped lattice structures () arranged on the flat surface between the waveguide ridges. The lattice structure () is formed on an insulating or barrier layer () at a distance from the laser layer above the laser layer (). Processes for the production of such a semiconductor laser are also disclosed.
