摘要
A semiconductor laser device having a real refractive index guided structure capable of obtaining a high kink light output and a high maximum light output also when a vertical beam divergence angle is at a small level of at least 12.5 and not more than 20.0 is provided. This semiconductor laser device comprises an n-type cladding layer of AlGaInP formed on an n-type GaAs substrate, an active layer having an AlGaInP layer formed on the n-type cladding layer, a p-type cladding layer of AlGaInP formed on the active layer and a light confinement layer formed to partially cover the p-type cladding layer, and a vertical beam divergence angle is at least 12.5 and not more than 20.0. Thus, a higher kink light output and a higher maximum light output can be obtained as compared with a conventional semiconductor laser device having a vertical beam divergence angle exceeding 20.0.
