Paper Abstract

The results of an investigation of optically pumped double-heterostructure lasers are reported. Threshold power densities of ≈8-35 kW cm-2 and a total power efficiency of ≈10% have been measured. Gain spectra have been derived from the data for several pumping configurations. Photogenerated carrier concentrations have also been calculated from the spectra. Current injection devices have been fabricated to assess the utility of this method for predicting lasing wavelengths and threshold current densities.
