LIGHT-EMITTING DEVICE AND HOLOGRAM REPRODUCER EMPLOYING THE LIGHT-EMITTING DEVICE

摘要

[PROBLEMS] To provide a light-emitting device in which variation in height of respective light-emitting points of a plurality of light-emitting elements can, especially, be reduced more appropriately and easily than conventional ones, and to provide a hologram reproducer employing such a light-emitting device. [MEANS FOR SOLVING PROBLEMS] The light-emitting device comprises a plurality of surface emission lasers (12, 13), and a supporting plate (50) for supporting each surface emission laser (12, 13) from the side of element surface (12b, 13b) where a light-emitting point (12a1, 13a1) appears. The surface (50a) of the supporting plate (50) facing the element surfaces (12b, 13b) is formed to have the same plane, and each element surface (12b, 13b) of the plurality of surface emission lasers (12, 13) is supported under the same plane (50a). Consequently, even when the thicknesses of the surface emission lasers (12, 13) are different, variation in height of respective light emitting points (12a1, 13a1) of the plurality of surface emission lasers (12, 13) can be reduced more appropriately and easily than conventional ones.
