摘要：
A red surface emitting laser element includes a first reflector, a second reflector including a p-type semiconductor multilayer film, an active layer between the first reflector and the second reflector, and a p-type semiconductor spacer layer between the active layer and the second reflector, the p-type semiconductor spacer layer having a thickness of 100 nm or more and 350 nm or less.
