The elastic behavior of the laser host crystal BaY2F8 doped with Tm and Dy has been investigated in the temperature range 288-308 K by using the ultrasonic pulse echo-overlap technique. Twelve propagation modes have been examined, which allowed the determination of 10 of the 13 independent elastic stiffness tensor components C-ij characterizing the monoclinic crystal lattice of BaY2F8. All the elastic constants associated with the examined propagation modes exhibit normal temperature dependence that is they increase with decreasing T.

Abstract
The elastic behavior of the laser host crystal BaY2F8 doped with Tm and Dy has been investigated in the temperature range 288-308 K by using the ultrasonic pulse echo-overlap technique. Twelve propagation modes have been examined, which allowed the determination of 10 of the 13 independent elastic stiffness tensor components C-ij characterizing the monoclinic crystal lattice of BaY2F8. All the elastic constants associated with the examined propagation modes exhibit normal temperature dependence that is they increase with decreasing T.File in questo prodotto:
