ABSTRACT:
Disclosed is a semiconductor laser device and manufacturing method thereof in which light absorption in a facet decreases and stable high power laser beam is generated. The semiconductor laser device having a stack structure in which a lower clad layer, an active layer, an upper clad layer, a current blocking layer, and a cap layer are sequentially formed, the semiconductor laser device includes: a Zn diffusion source layer on a facet of the stack structure; and a window layer between the Zn diffusion source layer and the stack structure, for preventing light absorption.
