abstract = "The performance of infrared (IR) nonlinear optical (NLO) materials is significantly affected by the thermal conductivity kL, but studies on the structure and property relationship of kL in these materials are very rare. In this work we evaluated the kL in IR NLO multicomponent chalcogenides LixAg1−xGayIn1−ySe2 with a smooth change in the compositions x and y by using a machine learning approach and laser flash measurements, combined with available experimental results. The found patterns of kL dependence on the atomic mass, bond length and electronegativity provide an effective understanding for navigation in the process of searching for new chalcogenide crystals with an optimal set of parameters that allow them to be effectively used as a frequency converter of laser radiation in the IR range. Moreover, the compositions Li0.5Ag0.5GaSe2, Li0.81Ag0.19InSe2 and AgGa0.5In0.5Se2 are demonstrated to exhibit a balanced combination of the parameters kL, NLO effects, energy band gaps, and birefringence for IR NLO applications.",

N2 - The performance of infrared (IR) nonlinear optical (NLO) materials is significantly affected by the thermal conductivity kL, but studies on the structure and property relationship of kL in these materials are very rare. In this work we evaluated the kL in IR NLO multicomponent chalcogenides LixAg1−xGayIn1−ySe2 with a smooth change in the compositions x and y by using a machine learning approach and laser flash measurements, combined with available experimental results. The found patterns of kL dependence on the atomic mass, bond length and electronegativity provide an effective understanding for navigation in the process of searching for new chalcogenide crystals with an optimal set of parameters that allow them to be effectively used as a frequency converter of laser radiation in the IR range. Moreover, the compositions Li0.5Ag0.5GaSe2, Li0.81Ag0.19InSe2 and AgGa0.5In0.5Se2 are demonstrated to exhibit a balanced combination of the parameters kL, NLO effects, energy band gaps, and birefringence for IR NLO applications.
