- Аннотация: The opportunity of growing of several centimeters in length LiGdF4 single crystals by Bridgman–Stockbargertechnique was demonstrated and the optically perfect LiGdF4 single crystals with 8 mm and 55 mm in lengthwere grown. The phase composition, thermal conductivity, basic optical and spectral-kinetic properties of LiGdF4single crystals were studied for the first time. For LiGdF4 crystal, the resulting linear thermal expansion coefficientsα is 11% larger, than for both LiYF4 and LiYbF4 crystals. The obtained thermal conductivity dependencek(T) is more pronounced compared to LiLuF4 and LiYF4. The absorption spectrum of the LiGdF4 crystal showsabsorption bands corresponding to the 8S7/2 – (6Dj, 6Ij, and 6Pj) transitions of Gd3+ ions. The measured roomtemperature lifetime of 6Pj multiplet of Gd3+ ions was equal to 4.25 ± 0.05 ms. The values of the temperaturegradient of the LiGdF4 refractive index do not strongly depend on the wavelength.
