摘要:

Constricted double‐heterojunction diode lasers have been life tested at 70 °C heatsink temperature and 3–4 mW/facet in cw operation. A median life of 7800 h is obtained at 70 °C, which extrapolates to 4×105h median life at room temperature. The extrapolated mean time to failure at room temperature is in excess of 106h. Single‐longitudinal‐mode cw operation is maintained after 10 000 h of accelerated aging at 70 °C.
