SEMICONDUCTOR LASER DEVICE

摘要

A semiconductor laser device includes a semiconductor laser chip configured to emit laser light forward in the emission direction and a stem having a tabular base whose thickness direction is in the emission direction. The base has a chip through-hole that passes through in the thickness direction. A part of the semiconductor laser chip is accommodated in the chip through-hole.
