摘要 | A semiconductor laser comprising an active layer having a light-emitting region of striped structure, a cladding layer formed on the active layer, another cladding layer formed under the active layer, the active layer being interposed between the cladding layer and the another cladding layer, facets formed on both ends of a stripe of the light-emitting region in which a part of light emitted is radiated, remaining light is refelected and amplifying the remaining light, wherein the semiconductor laser includes a means for having a minimum value of a coherence in a range between 2 mW and 7 mW of output of a light radiated from one of the facet which is a light output, and for preventing a phenomenon in which the output is reduced in a range at most 25 mW in accordance with an increase of the current, varied by a variation of a current applied to the active layer. |
其他摘要 | 一种半导体激光器,包括具有条纹结构的发光区域的有源层,形成在有源层上的包层,形成在有源层下面的另一个包层,有源层插入在包层和另一个包层之间,在发光区域的条纹的两端形成的小平面,其中发射的光的一部分被照射,剩余的光被反射并放大剩余的光,其中半导体激光器包括用于具有最小的相干值的装置。从作为光输出的一个面辐射的光的输出的范围在2mW和7mW之间,并且用于防止输出在至多25mW的范围内减小的现象随着电流随施加到有源层的电流的变化而变化。 |
