Abstract
In this paper high power diode array module with an emission wavelength of 1.06μm is presented. The epitaxial structure is an InGaAs/GaAsP strained-compensated single-quantum well structure. Laser bars with a fill factor of 50% arc processed and show a good temperature characteristics with a slope efficiency only decreasing from 1.08W/A to 1.06W/A when the temperature of heat sink changes from 20°C to 40°C. The module's CW output power can reach to 68.5W at a current of 80A when the temperature of cooling water is 20°C. The central wavelength is 1059.4nm.
