Paper Abstract

With the development of electronic device widely used in space and radiation environment, internationally, they are paying more attention to the research of electronic components resist radiation properties. In order to improve properties of anti-radiation semiconductor lasers, satisfy variable needs in space applications, 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) and discomposition and so on. And through adopt to the way of Super EBD(Electronic Brakeforce Distribution), coating Y2O3-ZrO2 film on the semiconductor lasers cavity surface to prove the ability of semiconductor lasers space resist radiation, use γray irradiation, analysis important indicator of laser like output power of coating film before and after, current power curve and so on.
