Abstract
A dual-beam laser diode is provided and includes a base, a first laser diode mounted on the base and having a laser emitting body controlled to emit a laser beam, and a second laser diode mounted between the base and the first laser diode and having a laser emitting body. The second laser diode has a laser emitting body spaced from the laser emitting body of the first laser diode within the range of 3 .mu.m to 5 .mu.m, and controlled to emit a laser beam partially overlapped on the laser beam of the first laser diode. The laser beams of the first laser diode and second laser diode can have different wavelengths and light spot patterns.
