A first contact surface of a semiconductor laser chip can be formed to a target surface roughness selected to have a maximum peak to valley height that is substantially smaller than a barrier layer thickness of a metallic barrier layer to be applied to the first contact surface. A metallic barrier layer having the barrier layer thickness can be applied to the first contact surface, and the semiconductor laser chip can be soldered to a carrier mounting along the first contact surface using a solder composition by heating the soldering composition to less than a threshold temperature at which dissolution of the metallic barrier layer into the soldering composition occurs. Related systems, methods, articles of manufacture, and the like are also described.
