ABSTRACT:
A semiconductor laser diode array is provided. The semiconductor laser diode array includes: a lower semiconductor laser diode chip having a dual structure including a lower substrate, a first laser generating region disposed on the lower substrate, and a second laser generating region disposed on the lower substrate and separated from the first laser generating region; an upper semiconductor laser diode chip having a dual structure including an upper substrate, a third laser generating region disposed on the upper substrate, and a fourth laser generating region disposed on the upper substrate and separated from the third laser generating region; and an electrode unit electrically connecting the first through fourth laser generating regions to the outside. The first and second laser generating regions are vertically bonded to the third and fourth laser generating regions, respectively, so that the first through fourth light-emitting points in the first through fourth laser generating regions from which laser beams are emitted are arranged in a two-dimensional fashion.
