A high continuous-wave (CW) power of 6 W at 626 nm and 15 W at 637 nm with 15 and 30% power conversion efficiencies, respectively, has been demonstrated from AlGaInP/GaInP laser diode arrays. Fibre-coupled 630 nm CW bars demonstrate good reliability at 3 W. Such devices are useful for photo-dynamic therapy (PDT) or display applications.
