英文摘要 | There is provided a semiconductor laser device, which has an oscillation wavelength that is greater than 760 nm and smaller than 800 nm, high reliability, long operating life and a high output, and an optical disk reproducing and recording apparatus that employs the semiconductor laser device. At least first and second lower clad layers 103 and 133, a quantum well active layer 105 constructed of well layers and barrier layers, first and second upper clad layers 107 and 109 are laminated on a GaAs substrate 10 The well layer is made of InGaAsP. The well layer has a great layer thickness d of 160 Å, and assuming that an optical confinement coefficient in one layer of the well layer is GAMMA, then GAMMA/d is set at a great value of 2.2x10-4 Å- |
