Abstract

The new laser crystals BeLaAl₁₁O₁₉ doped with Cr³⁺, Ti³⁺ and Nd³⁺ ions were grown by the Czochralski technique. The absorption and fluorescence spectra of impurity ions are reported and the temperature dependence of the fluorescence lifetime are described. The laser properties of these ions were investigated. The laser action has been achieved on ⁴F_3/2-⁴I_11/2 (1052 nm) transition of Nd³⁺ -ions under selective laser pumping. The physical properties of BeLaAl₁₁O₁₉ crystal were studied: the values of all independent component of elastic constant tensor were determined. On the base of a number of dynamic parameters of crystals, such as Young's modulus, the shear modulus, the volume elasticity modulus and Poisson's factor, Debye temperature and specific heat capacity were calculated. The investigation show that the BeLaAl₁₁O₁₉ is a promising host for a creature the new solid state laser media.
