Fabry–Perot quantum cascade lasers (QCLs) were characterized following irradiation by high-energy (64 MeV) protons and Cobalt-60 gamma rays. Seven QCLs were exposed to total accumulated radiation doses that varied from 20 to 46.3 krad(Si), which are typical exposure levels for electronic components in a space environment. The QCLs did not show any measurable changes in threshold current or slope efficiency suggesting the suitability of QCLs for use in space-based missions.
