Paper Abstract

The attenuation of diode laser bar depends on the level of productive art and working condition, and the devices which attenuate quickly appear higher junction temperature and asymmetry of heat distributing. This paper introduces the research on the attenuation character of GaAs/AlGaAs diode laser bar, and obtains imitate curve of relation between PN junction voltage and junction temperature through plentiful experiments. At the same time, we draw the instantaneous thermal resistance through calculation. Based on the electrical method instantaneous thermal resistance and aging experiment, we have realized evaluating the attenuation character of diode laser bar without any damnify. Moreover, we have raised modification measure which based on analyzing the correlative art.
