Abstract
We demonstrate an integrated all-fiber mid-infrared (mid-IR) supercontinuum (SC) source generated by a 1.95 μm master oscillator power amplifier system and a single-mode ZBLAN (ZrF4–BaF2–LaF3–AlF3–NaF) fiber. The maximum average output power is 10.67 W with spectral bandwidth covering from ～1.9 to 4.1 μm. The single-mode ZBLAN fiber and silica fiber are thermal-spliced to enhance the robustness and practicability of the system. It is, to the best of our knowledge, the first high-power integrated compacted all-fiber mid-IR SC source based on thermal-spliced silica fiber and ZBLAN fiber.Postdoctoral Science Foundation (2015M572353, 2015M582407); Natural Science Foundation of SZU (201457); National Natural Science Foundation of China (NSFC)(61275144, 61308049); Science and Technology Projects of Shenzhen City (JCYJ20130329103213543, JCYJ20140418091413568, JCYJ20150324140036862).
