英文摘要PURPOSE:To obtain a semiconductor laser element with a large output and stable operation at a short wavelength region by constituting a semiconductor activation layer region with three mixed crystal quantum well layers, two barrier layers separating them, and a light guide layer, and then by achieving a specific composition. CONSTITUTION:An n-GaAs buffer layer 2, an nAlXGa1-xAs clad layer 3, an AlYGa1-YGa1-YAs light guide layer, an AlUGa1-UAs well layer, a multiplex quantum well type activation layer 4 which consists of an AlWGa1-WAs barrier layer, a p-AlXGa1-XAs clad layer 5, and a p-GaAs interface layer 6 are formed on an n-type GaAs substrate This semiconductor laser has a wavelength of approximately 780nm, a threshold current value of approximately 35mA, and a horizontal basic mode. Also, it oscillates stably up to 70mW, does not show any deterioration at a lapse of 1000 hours or longer in continuous operation test of 50mW at 50 deg.C, and has an improved reliability.
