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
Single crystals of Ytterbium doped KGd(WO 4 ) 2 were grown by Top Seeded Solution Growth technique using K 2 WO 4 as flux system. The growth parameters were optimised to get optically transparent crystals. Variation in the lattice parameters were observed in comparison to the pure KGd(WO 4 ) 2 cryst
