Growth and characterization of large SrMoO4 crystals
Crack-free SrMoO4 single crystals with high optical quality and large dimensions (empty set 40 x 45 mm(2)) were successfully grown along a- and c-axis by the Czochralski method. X-ray powder diffraction results show that the as-grown SrMoO4 crystal belongs to the tetragonal system in the scheelite structure. The result of the rocking curve shows that the symmetry of the diffraction peak is fairly favorable and the full width at half-maximum value was measured to be 94.68 ''. The density of the as-grown crystal was measured to be 4.683 g cm(-3) agreeing well with the theoretical one. Their transmission spectra was measured at room temperature over the wavelength range of 300-3000 nm and the results indicate that the transmittance of SrMoO4 single crystal is more than 80%, which suggests that the SrMoO4 crystal has good quality. All the results mean that this crystal should be an excellent Raman material suitable to be used in the operation of stimulated Raman lasers. (C) 2010 Elsevier B.V. All rights reserved.
