More info

Barium Gallium Selenide (BGSe) Crystal is a nonlinear optical material synthesized using the Bridgman-Stockbarger method. Its large crystal size allows for the measurement of dispersion and refractive coefficients, which are vital for predicting phase interaction properties. BGSe shares similarities with BGS crystal and holds great potential for nonlinear optical applications. Heeger Materials (HM) provides high-quality BGSe crystals for advanced research and industrial use.
