Abstract

To verify the potential space radiation-induced degradation of optical satellite communication system, the $\gamma$ ray radiation experiment of the 850nm laser diode have been designed through irradiating the diode with a radiactive source of Co-60, indeed we analyze the initial light output and the light output after irradiation at  room temperature, in turn We develop a degradation equation of the signal: \begin{center}\begin{math}[{I_0}/{I}]^n -1 &= K$\tau$_0 $\Phi$\end{math} \end{center} \newline
No obvious performance degradations of the diode laser were found at the total dose less than 2 kGy.
It is believed that the high energy particles’ radiation effect should be first considered when it refers to the optical terminals’ applications in the space.
