Temperature-dependent phase-matching properties of BaGa2GeS6 in the 0.767-10.5910 µm spectral range

Appl Opt. 2022 Dec 20;61(36):10774-10777. doi: 10.1364/AO.476853.

Abstract

We report experimental results on the temperature-dependent phase-matching properties of BaGa2GeS6 for second-harmonic generation and sum-frequency generation in the 0.7674-10.5910 µm range. We also derive refined Sellmeier and thermo-optic dispersion formulas that provide a good reproduction of the present experimental results.
