Abstract
A light emitting device includes: a base including a first wiring, a second wiring, and a third wiring; a first semiconductor laser element electrically connected to the first wiring and the second wiring, at an upper surface side of the base; and a second semiconductor laser element electrically connected to the second wiring and the third wiring, at the upper surface side of the base. The base includes a frame surrounding the first semiconductor laser element and the second semiconductor laser element in a top view. The light emitting device further includes a base cap fixed to the frame such that the first semiconductor laser element and the second semiconductor laser element are enclosed in a space defined by the base and the base cap. The first semiconductor laser element and the second semiconductor laser element are connected in series.
