Abstract
Premature catastrophic degradation in sawn-cavity (GaAl)As/GaAs heterostructure lasers can be attributed to the presence of internally circulating modes. When lasers were selected for good near-field uniformity and assumed freedom from internally circulating modes, good agreement was obtained between the power at catastrophic degradation and the effective optical width perpendicular to the junction.Keywords
