ABSTRACT:
A semiconductor laser beam device, comprising a stem type package having a base part and a heat sink part, wherein the heat sink part is cylindrically formed so as to be concentric to the base part, a groove is formed along the axial direction of the heat sink part, and a semiconductor laser beam element is disposed at the bottom part of the inner wall surfaces of the groove whereby the radiating capability of the semiconductor laser beam device can be increased by increasing the volume of the heat sink part, and the element can be protected by the groove.
