Physical properties of optically uniaxial BaLa_{1-x}Nd_{x}Ga_{3}O_{7} crystals have been investigated. Specific heat, thermal expansion coefficients, thermal diffusivity, Young modules and Poisson ratios of the crystal have been determined. Basing upon these parameters and the available spectral data the operating conditions for lasers employing rods made of BaLa_{1-x}Nd_{x}Ga_{3}O_{7} have been defined.
