✦ Synopsis

The study of KGW: (Er, Yb) was performed for the acoustic phonons [1 0 0], [0 0 1], [Γ€1 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 phonons which is characteristic for low symmetry crystals. Moreover, it has been revealed, that the value of Brillouin shift and integral intensity of the longitudinal phonon [1 0 1] propagating in KGW: (Er, Yb) show the anomaly at about 175 K.

Study of the elastic properties of SrLaAlO 4 (SLA) and SrLaGaO 4 (SLG) crystals has been reported. The absorption of the yellow and green SLA and SLG crystals in the visible range was also investigated. The results obtained are discussed in terms of the nature of the oxygen point defects, which migh
