Semiconductor laser having light feedback function |
摘要 |
<p>A semiconductor laser module is provided for emitting pumping laser light which excels in temporal stability. The semiconductor laser module comprises a semiconductor laser device which has a layered structure formed on a GaAs substrate, wherein the layered structure has an active layer in a quantum well structure, formed of semiconductor materials including Ga and As, and a member having a light feedback function. The two components are optically coupled. A well layer in the active layer of the semiconductor laser device is a thick layer having a thickness of 10 nm or more. The active layer is doped with Si, and an n-type cladding layer underlying the active layer is also doped with Si. <IMAGE></p> |
