Semiconductor laser device

Abstract

The present invention includes a semiconductor laser element, a lead, a first packaging member and a second packaging member. The lead includes a mount surface for supporting the semiconductor laser element. The first packaging member includes a first wall and a second wall. The first and the second walls are spaced from each other in a direction that is along the mount surface and crosses a laser beam emission direction of the semiconductor laser element, with the semiconductor laser element arranged between the first and the second walls. The second packaging member is pressed in between the first and the second walls and faces the mount surface and the semiconductor laser element.
