Abstract :
We present an evaluation of the effects of proton and gamma irradiation on the performance of GaSb-based 2.1 μm laser diodes lasers for space applications. The study is focused on the effects of radiation on the Power-Current, Current-Voltage and Wavelength-Current-Temperature characteristics of the lasers. No significant radiation damage has been found.
