摘要
In a semiconductor laser element including a multilayered structure being formed of a plurality of semiconductor layers made of a plurality of group III-V compounds, and having at least a pair of cleaved end surfaces as a pair of light resonator surfaces, a first reflectance control layer, made of an oxygen gettering material which has a function of gettering oxygen, is formed on at least one of the pair of light resonator surfaces, and a second reflectance control layer made of a nitride of a group III material is formed on the first reflectance control layer.
