摘要：

The BaWO4 and SrWO4 crystals doped with Nd3+ have been grown and investigated as matrices for laser active elements with nonlinear self-conversion of radiation to a new spectral range. Results on the growth technique, spectral and luminescence characteristics of Nd3+ ions in BaWO4 and SrWO4 Raman crystals are presented. Conditions were found to obtain optical homogeneous single crystals free of light scattering centers and growth striations. Values of effective segregation coefficients of active (Nd3+) and compensating (Nb5+, Na+) ions were determined using the results of spectral emission analysis. The refraction index dispersion in the visible range was measured for both materials. The absorption and luminescence spectra are presented.
