Abstract: Specific features of degradation of the GaAlAs and InGaAsP heterojunction lasers are studied during aging at 60 °C and upon irradiation by fast particles. Analytic expressions are obtained that describe an increase in the dispersion of the threshold current distribution with the time of the operating-life test and the dose of irradiation by fast particles.
