摘要:

The facet deterioration of (AlGa)As DH lasers by aging was analyzed by Auger electron spectroscopy in combination with Ar sputter etching. It was found that oxide was formed on the laser facet during cw operation, and the oxidation degraded lasers not only in long‐term operation but also even at an early stage of operation.
