Near infrared (765 nm) AlAs/AlGaAs vertical-cavity surface emitting laser (VCSEL) diodes with minimum threshold currents of 0.6 mA and threshold voltages of 1.9 V are demonstrated. The peak output powers exceed 5 mW. These characteristics represent a significant improvement compared to previously published data for VCSELs operating in this wavelength range
