The degradation rates for continuously operated quantum well lasers with natural facets have been investigated. For most devices, a simple functional relationship exists between degradation rate and operating current density and the data suggest that the role of optical flux is secondary. For device configurations with high excess nonradiative current densities, however, exceptionally high degradation rates are observed and a correlation is proposed.
