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. M
The study of KGW: (Er, Yb) was performed for the acoustic phonons [1 0 0], [0 0 1], [ร1 0 1], [1 0 1], [1 1 0] and [0 1 1]. In some Brillouin spectra obtained at room temperature we observed additional modes connected with mixed polarization modes propagating as quasilongitudinal or quasi-transverse
