Chalcogenide fibers have been used in laser processing, laser surgery, and homeland security. The development of chalcogenide fibers with low loss and high laser damage threshold has great scientific value and application prospects. In particular, hollow-core micro-structured fibers are a technological race for the next generation of infrared fibers and related applications.
