Abstract
A light-emitting device includes a plurality of semiconductor laser elements including a first semiconductor laser element, and a plurality of reflectors including a first reflector for reflecting light emitted from the first semiconductor laser element, each of reflectors reflecting light emitted from corresponding one of the plurality of semiconductor laser elements. Light emitted from the first semiconductor laser element passes through a gap between two of the plurality of reflectors excluding the first reflector and reaches the first reflector. Lights emitted from the plurality of semiconductor laser elements are extracted in a direction different than an incident direction thereof toward the plurality of reflectors.
