Abstract
Identification of a major failure mechanism in stripe-geometry proton-bombarded double-heterojunction lasers is reported. This mechanism consists of the formation of localized "dark lines" in the optical cavity, coinciding with a decrease in light output. The dark lines are aligned in 〈100〉 crystallographic directions.
