Performance of 3-W/100-μm stripe diode laser at 950 and 810 nm

In this paper we report on Al-free InGaAs/InGaAsP/InGaP broad area laser diodes emitting at 950 nm and on 810 nm- laser diodes with Al-free GaAsP quantum wells in AlGaAs waveguides. 2 mm long diode lasers show a high wall plug efficiency above 50% at output powers of about 3 W. The beam characteristics of these diode lasers benefit from small confinement factors. Results depending on stripe width and resonator length are given.
