Al-free active-region (λ=805 nm) diode lasers with 1 μm thick InGaP waveguide layers provide continuous wave powers as high as 8.8 W from 1.25 mm long devices with 4%/95% facet-coating reflectivities and 100 μm wide stripes. The transverse beam pattern is Gaussian-like with a 36° beamwidth and the series resistance is only 48 mΩ
