Abstract

Spectroscopic characteristics of intracenter transitions in disordered crystals of sodium-yttrium double fluoride Na_0.4Y_0.6F_2.2: Pr3+ with cubic structure, grown by Stockbarger-Bridgeman method, are investigated theoretically and experimentally in order to evaluate their potential for application as active media of solid state lasers emitting in visible spectral range.
