ARRAY TYPE OPTICAL COMPONENT AND METHOD FOR MANUFACTURING THE SAME, AND OPTICAL SYSTEM FOR ARRAY TYPE SEMICONDUCTOR LASER

摘要

An array type optical component is constituted by stacking a plurality of triangular prismatic unit transmission optical elements each having a light incident face (3a) receiving the output light from an array type semiconductor laser (1), a light reflecting face (3b) for reflecting the light refracted on the light incident face (3a), and a light exit face (3c) for refracting the light reflected on the light reflecting face (3b) such that the light reflecting faces (3b) are substantially parallel. Assuming the arranging direction of light emitting points of the array type semiconductor laser (1) is X direction, traveling direction of the output light is Z direction, and the direction perpendicular to the X direction and the Z direction is Y direction, the light reflecting face (3b) of each unit transmission optical element is arranged to be in parallel with the Z direction and to intersect the X-Z plane at substantially 45°. An array type optical component and an optical system for an array type semiconductor laser in which the output light from an array type semiconductor laser can be converted to an isotropic condensing light beam are thereby obtained through a relatively simple arrangement.
