ϕ60mm大尺寸红外非线性BaGa4Se7晶体与器件制备
Fabrication of ϕ60 mm Large-Size Infrared Nonlinear BaGa4Se7 Crystals and Devices
摘要
Abstract
Barium gallium selenide(BaGa4Se7,BGSe)crystal is a novel infrared nonlinear optical material with excellent comprehensive properties.The current research priority lies in the preparation of large-size,high-quality BGSe crystals.The synthesis of high-purity BGSe polycrystalline raw materials over 500 g was achieved in a single batch using a two-temperature zone synthesis furnace.Subsequently,BGSe crystal boules with a diameter of ϕ60 mm were successfully grown via an modified Bridgman method.Through orientation,cutting,and polishing processes,laser frequency conversion devices measuring over 10 mm×10 mm×50 mm were fabricated.The prepared crystals and devices represent the largest dimensions reported to date,providing critical material and component support for mid-to long-wave infrared laser output.关键词
