Thermo-Mechanical Characterization of the Orthorhombic Nonlinear Optical Crystal PbGa<sub>2</sub>GeSe<sub>6</sub>

Thermo-Mechanical Characterization of the Orthorhombic Nonlinear Optical Crystal PbGa<sub>2</sub>GeSe<sub>6</sub>

Linear thermal expansion in the 70–350 K range and nanohardness and Young’s modulus at room temperature are measured for the newly developed quaternary nonlinear optical crystal PbGa<sub>2</sub>GeSe<sub>6</sub> applicable in the mid-IR part of the spectrum (3–25 µm).
