  • Semiconductor laser for high optical output power with reduced mirror heating
    Patent number: 4722088
    Abstract: The semiconductor laser, which can be either electrically or optically pumped, characterized by quantum well structure for the body and by having a distance of the respective mirror structures from the end of the laser active zone which is dimensioned within tight limits. The structure provides a semiconductor laser in which problems with destruction or aging of the reflective properties of the mirror structure due to heating are reduced.
