An effective diffusion rate of Nd3+ ions was experimentally determined in polycrystalline matrix YAG, which was 1.5x10-15 м2/с. It was found that activation of YAG by Nd3+ ions leads to an increase in the lattice parameter. The dependence of the characteristics of laser generation Nd3+:YAG ceramics on the activator concentration was investigated. A new method of quantitative evaluation of the porosity of transparent materials was proposed.
