摘要

A large optical cavity diode laser has been developed operating at 1070 and 1118nm using partially strain-balanced DQW gain regions of GaAs_(0.94)P_(0.06)/In_xGa_(1-x)As (x = 0.24 and 0.29). TEM has been used to characterise the QWs for interface roughening resulting from the high residual compressive strain. For both wavelengths, oxide-defined stripe-contact devices show comparable slope efficiencies and T _0 values. In the case of the 1070 nm laser, the operating lifetime at 15℃ was in excess of 4600h for an output of 1.5 W and degradation rate of 2 x 10~(-5)/h.
