โœฆ Synopsis

In this paper we present the study of the acoustic phonons propagating in Er 3+ -doped KGd(WO 4 ) 2 single crystals by Brillouin spectroscopy. For the investigated crystals the velocities of the longitudinal and transverse acoustic phonons [100], [010], [001], [101] and [110] have been determined. Moreover, the values of the elastic constants: C 22 , C 44 and C 66 of Er 3+ -doped KGd(WO 4 ) 2 single crystals have been estimated. It was revealed that the presence of the Er 3+ -ions in KGd(WO 4 ) 2 crystals, for the used doping concentration 1 at% does not influence their elastic properties.
