Research on radiation effect and reinforce of radiation resistance for semiconductor lasers

This paper introduces the space radiation environment, and its influence on the semiconductor lasers, analysis generating mechanism which is including total dose effect of radiation, SEU (Single Event Upset), Displacement effect and The surface charge and discharge effect. And through adopt to the way of E-beam evaporator, depositting Y2O3-ZrO2 film on the semiconductor lasers cavity surface to prove the ability of semiconductor lasers space resist radiation, use γ-ray irradiation, analysis important indicator of laser like output power of deposit film before and after, current power curve and so on.
