| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a semiconductor laser element which can achieve TM mode oscillation and which has high reliability.SOLUTION: A semiconductor laser diode 70 comprises: a substrate 1; and a semiconductor stacking structure 2 which is formed on the substrate 1 and includes an active layer 10. The active layer 10 has a multiquantum well structure in which quantum well layers 221 each composed of an undoped GaAsPlayer (0 |
