In this work we present results on YAG:V3+ single crystal growth and examination for the purposes of Q- switching of laser resonator in the near IR band. A number of YAG single crystals doped with different concentrations of V3+ ions were obtained by the Czochralski method. The absorption and emission spectra measurements on those crystals are presented. After crystal growth only a small part of vanadium atoms is introduced into a crystal structure as V3+ ions in tetrahedral positions, the other ones are at different positions or at higher charge states V4+ and V5+. Receiving of vanadium ions of V3+ valency in the desired points of YAG structure can be possible as a result of complex reactions in solid- state phase. Such reactions proceed during the process of a multi-stage crystal annealing in reducing atmosphere and in vacuum.
