TL;DRAbstract

We show tlat DX-like centers in Cd1-xMn xe1-ySex:In crystal can be used in writing volume holographic gratings. Tle scattering efficiency is higher than 10% which proves the dispersive character of the light-induced gratings. Two different metastable centers with different 1attice relaxation were found in the crystal. Measurements of the power dependence of the degenerate four-wave mixing scattering efficiency testify that both of these centers have negative U properties.
