摘要：

Aging characteristics of Ga1-xAlxAs DH lasers bonded with gold eutectic alloy solder and indium solder were studied. In the lasers bonded with indium solder, it was found that thermal resistance increased during the aging test and the activation energy for the increasing rate of thermal resistance was 0.6 eV. Sixteen lasers bonded with gold-tin eutectic alloy solder have been operating at 70°C over 1800 h with no increase in thermal resistance and a slight increase in the driving current required to maintain the cw optical power constant during the aging test; and lasers bonded with gold-germanium eutectic alloy solder have been operating at 70°C over 10 000 hours with a slight increase in driving current. The use of gold eutectic alloy solder makes possible the long-lived lasers.
