| Zusammenfassung: | PURPOSE:To prolong the life of a group II-VI semiconductor laser and improve the reliability of the laser. CONSTITUTION:A gettering heater 16 is provided in the interior 17a of a sealed container 17 encapsulated with inert gas along with a semiconductor laser chip 11 and after the assembly of a semiconductor laser is completed, a prescribed current is made to flow through the heater 16, active impurity gas in the interior 17a of the container 17 reacts with the material of the heater 16 and the impurity gas is removed from the interior 17a of the sealed container 17. |
