Popis: The present work is devoted to investigation of optical absorption in pure and neodymium-doped YAlO3 (YAP) single crystals in the spectral range 0.2–1.1 μm induced by the influence of 12C ions irradiation with energy 4.50 MeV/u (MeV per nucleon) and a fluence 2 × 109 cm−2 or of 235U ion irradiation with energy 9.35 MeV/u and a fluence 5 × 1011 cm−2. The induced absorption in the case of 12C ions irradiation is caused by recharging of point growth defects and impurities under the radiation influence. After irradiation by 235U ions with fluence 5 × 1011 cm−2 the strong absorption rise is probably caused by contribution of the lattice destruction as a result of heavy ion bombardment.
