## Abstract Nitride laser diodes and light emitting diodes were irradiated with 200‐, 80‐ and 10‐MeV protons. The threshold current of violet laser diodes increased with increasing proton fluence to 1 Γ— 10^14^ p/cm^2^. The increase in threshold current is considerably small compared with that of Al
