ABSTRACT:
In a laser diode element including a front facet, a rear facet, a laser cavity formed between the front rear facets and which has a predetermined length L, coating layers coated on the front facet to provide a reflectivity smaller than 5%, and an active layer and a uniform grating having regular corrugation formed in the direction of the layer cavity and which are coupled to each other at a predetermined coupling constant K, the laser diode element is specified by a product of the predetermined coupling constant and the predetermined length L and falling within a range between 0.4 and 1.0, both inclusive.
