Photoinduced coloration and the holographic grating recording associated with it are experimentally studied in Mn-doped yttrium orthoaluminate (Mn:YAlO<sub>3</sub>). High diffraction efficiency is demonstrated in visible and in infrared light. The diffraction efficiency at 514.5 nm exceeds 50%. The strong energy exchange between the writing beams observed in a two-wave mixing experiment suggests that diffraction in Mn:YAlO<sub>3</sub> is due to mainly nonlocal holographic effect and an electro-optical effect. Mn:YAlO<sub>3</sub> is shown to be a promising material for holographic recording and optical storage.
