Thermo-mechanical properties of the Ba <sub>2</sub> Ga <sub>8</sub> GeS <sub>16</sub> nonlinear optical crystal
Linear thermal expansion in the 76-310 K range, and nanohardness and Young’s modulus at room temperature are measured for the newly developed quaternary nonlinear optical crystal Ba 2 Ga 8 GeS 16 with hexagonal symmetry, applicable in the mid-IR part of the spectrum. The results reveal quasi-isotropic behavior of all these properties.
