مستخلص: | Al-free active-region diode lasers grown by low-pressure, metal-organic chemical vapor deposition and emitting at λ=805 nm have been optimized for high continuous wave output power. The 1-mm-long devices consisting of an InGaAsP/In[sub 0.5]Ga[sub 0.5]P/In[sub 0.5](Ga[sub 0.5]Al[sub 0.5])[sub 0.5]P laser structure have a threshold-current density, J[sub th], of 310 A/cm[sup 2] and relatively high values for the characteristic temperatures of the threshold current, T[sub 0] (135 K), and differential quantum efficiency, T[sub 1] (900 K). Lasers with 10%/90% coatings and a 100-μm-wide stripe provide a maximum cw output power of 6.1 W at a heatsink temperature of 10 °C. The devices fail due to catastrophic optical mirror damage (COMD), where the internal power density, P¯[sub COMD], is 17.4 MW/cm[sup 2]; that is, twice that for conventionally facet-coated, 810 nm emitting, AlGaAs active-region diode lasers. © 1998 American Institute of Physics.
