Abstract :
100 μm-wide stripe, 0.97 μm-emitting Al-free InGaAsP-InGaP-GaAs QW lasers, demonstrate a record value for quasi-CW output power, 14.3 W, low internal losses (α=1 cm-1), and high differential quantum efficiency (86% for 2 mm-long lasers). Long cavity, large-stripe devices exhibit relatively small spectral broadening with increased output power
