Abstract:
1. A surface emitting laser element, comprising: a substrate made of GaAs; a lower multilayer film reflecting mirror formed on the substrate and formed of a periodic structure of a low-refractive-index layer made of Al an upper multilayer film reflecting mirror provided above the lower multilayer film reflecting mirror, and formed of a periodic structure of a low-refractive-index layer and a high-refractive-index layer; an active layer provided between the lower multilayer film reflecting mirror and the upper multilayer film reflecting mirror; and a p-side electrode and an n-side electrode which are provided above the substrate, and configured to inject an electric current into the active layer, wherein the lower multilayer film reflecting mirror is added with an n-type dopant, and a warp of the substrate is equal to or more than a warp of δ in μm defined by equation (1) below, where x
