Multiple layers of InP QDs, self-assembled during epitaxial growth, were incorporated into the active region of an (AlxGa1-x)(0.51)In0.49P based semiconductor disk laser with monolithic AlxGa1-xAs distributed Bragg reflector. Three gain structure samples were selected from the epitaxial wafer, bonded to single-crystal diamond heatspreaders and optically pumped at 532nm within a high finesse external laser cavity. Laser emission with peak wavelengths at 716, 729, and 739 nm, respectively, was achieved from the three samples; the latter demonstrating tuning from 729 to 755 nm. Maximum continuous wave output power of 52mW at 739nm was achieved with 0.2% output coupling; the threshold and slope efficiency were 220 mW and 5.7% respectively.
