AlF3 Fluoride Fiber
AMF-xxx-yyy
FiberLabs' AlF3-based fluoride fiber has been widely used as an optical guide for 2.94-μm Er-YAG medical laser instruments (dentistry, cosmetic sergery, etc.). This is because AlF3-based fluoride fiber, compared to ZBLAN fiber, shows better environmental stability in terms of laser damage thresholds and resistance against water. In addition, the trasmission loss is lower than that of GeO2 fibers at 2.94 μm.
This fiber can also be used as an optical guide for wide-band spectroscopy because of its wide transmission window from 0.3 to 3.5 μm.
