In the deuterium treatment step, a deuterium concentration D in the treatment chamber during the deuterium treatment is calculated from an initial value A of a deuterium concentration in the deuterium containing gas inside the treatment chamber, a concentration B of oxygen in an ambient atmosphere of the treatment chamber, and a concentration C of oxygen in the deuterium containing gas inside the treatment chamber, and the deuterium concentration in the treatment chamber is controlled based on the deuterium concentration D calculated. Other gases such as hydrogen containing gas or nitrogen containing gas may also be used according to the invention.

摘要： A semiconductor laser device includes an active layer and first and second current blocking layers having aligned stripe openings for injecting operating current into the active layer in a current injection area. The second current blocking layer has another opening, through which the first current blocking layer contacts an external cladding layer, in the vicinity of the emission facet of the laser cavity to form a current non-injection area. The first current blocking layer and the external cladding layer have a substantially equal refractive index.
