Abstract:LiGa 0.5 In 0.5 Se 2 is a new quaternary nonlinear optical crystal for the mid-IR application grown as a mixed crystal of the LiGaSe 2 −LiInSe 2 solid−solution system. It is transparent in the 0.47− 14 μm range and has an appropriate bandgap and a lower melting point than LiGaSe 2 and LiInSe 2 . It is more technological about the growth process since its homogeneity range is broader in the phase diagram. In this work, we have synthesized the LiGa 0.5 In 0.5 Se 2 polycrystal by the two-zone temperature method. … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
