Abstract:The lead-free double-perovskite Cs4CuSb2Cl12 is used for Q-switched mode-locking an Yb-doped fiber laser with ∼1 μm NIR modulation, high pulse-energy operation and low saturation power, showing huge potential for integration into photonic devices.
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.
