“…For this reason, the large difference of the refractive indices obtained in the present study and in Refs [10,11] from the indices given in Ref. [12] can be explained by the difference between the compositions of the investigated crystals, particularly since crystals of rare-earth garnets are solid solutions with a wide amorphous substitution region [13]. Table 3 gives the refractive indices n o and n e of Tm: GdVO 4 (4% Tm) and Er: GdVO 4 (30% Er) crystals.…”

The refractive indices of new Nd 3+ : GdVO 4 , Tm 3+ :GdVO 4 , and Er 3+ :GdVO 4 laser crystals were determined with an error of ±5 x 10~5 in the range 400-1100 nm. The birefringence of these crystals was on the average 0.24, and the dispersion was described by the formula I/An 2 = a + b/k 2 . The thermal conductivity of the Nd:GdVO 4 crystal (atomic neodymium concentration 1.3%) was determined in the temperature range 77-300 K. At 300 K the conductivity along the (110) direction was 11.7 W nT 1 K" 1 , which was higher than the conductivity of Nd: YAG crystals.

“…Such graphic presentation is very convenient and allows rather fast determination of the congruently melting composition, like it has been previously demonstrated for rare‐earth‐scandium garnets using some other premises. [ 32 ] This method of steep ascent in finding of congruent‐melting composition could be applied also to other complex systems.…”

The concentration series of sodium‐gadolinium molybdate (NGM) crystals have been grown by Czochralski technique from stoichiometric Na0,5Gd0,5MoO4 melt, and from seven different nonstoichiometric melts in various atmospheres. The actual cation compositions of the crystals are measured by microprobe analysis. The location of the congruently melting composition is found for this compound, and the homogeneity field is evaluated. The unit cell parameters of the crystals have been calculated from X‐ray diffraction (XRD) analysis results. Hydrostatic densities of the crystals are measured. Based on these results, the actual molar weights of the samples are calculated that allows more precise determination of the crystals compositions. The studied crystals are shown to contain substantial sodium deficiency and excess of gadolinium compared to stoichiometry. The amount of cation vacancies occurs in both sublattices along with increase of Gd2O3/Na2O molar ratio in the crystals.

“…Nd 3+ -doped yttrium scandium aluminum (Nd:Y 3 Sc x Al 5-x O 12 ) compositions are considered as solid solution of Nd:YAG and Nd:Y 3 Sc 2 Al 3 O 12 (Nd:YSAG) [3]. These crystals have some advantages in comparison to Nd:YAG crystal [4][5][6][7][8]. In the lattice, Sc 3+ and Al 3+ ions are randomly distributed on the octahedral positions.…”

“…Nd:Y 3 Sc x Al 5-x O 12 crystals has been grown by the Czochralski method [6], floating zone method [7] and micro-pulling-down method [8]. The μ-PD method has the capability to produce under stationary stable regime single crystalline materials quickly, relatively inexpensively and the grown samples are of sufficient dimensions for the microscopic and macroscopic characterization [9][10][11][12].…”

Nd 3+ doped Y 3 Sc x Al 5-x O 12 (x= 0.05, 0.5, 1) single crystals were successfully grown by the micro-pulling-down (μ-PD) technique. The effect of compositional parameter x on the structure, absorption, emission and fluorescence lifetime of Nd:Y 3 Sc x Al 5-x O 12 crystals was studied. The Nd 3+ concentration in the core increased with increasing of compositional parameter x. The full width at half maximum (FWHM) of the emission band centered at 1064 nm was calculated to be 6.1, 7.1, and 7.3 nm for x= 0.05, 0.5 and 1, respectively. The fluorescence lifetime of 4 F 3/2 levels are 259.3, 269.6, and 276.9 μs for x= 0.05, 0.5, and 1, respectively. The results indicate that the Nd:Y 3 Sc x Al 5-x O 12 crystals are promising materials for laser output.
