Abstract
A light-emitting module includes: first and second light-emitting devices each including semiconductor laser elements that emit laser beams with an interval in a slow axis direction of the laser beams; a first optical unit that includes one or more first reflective members provided with reflective surfaces on which laser beams are incident and that makes the interval of the laser beams smaller and emits the laser beams; a second optical unit that includes second reflective members provided with reflective surfaces on which laser beams are incident and that reflects, two times or more, laser beams emitted with an interval in a fast axis direction and emits the laser beams with a smaller interval and with a smaller width in the fast axis direction of the laser beams; and a condenser lens that gathers laser beams having traveled through the first optical unit and the second optical unit.
