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.
