Abstract

A semiconductor laser device comprises a semiconductor laser chip, a first member which has one surface substantially perpendicular to a direction of an emission laser beam and has a concave having a bottom face substantially parallel to the one surface, and a second member inserted into the concave and joined to the first member. The semiconductor laser chip is disposed to the bottom face of the concave of the first member. The second member is inserted and joined into the concave of the first member so as to cover the semiconductor laser chip. Consequently, it is avoided to impair smoothness of the one surface of the first member, so that it is possible to precisely join the first and second members after being joined together to a desired apparatus at the one surface.
