Specialty Fibers
FiberLabs' fluoride fiber materials business: ZBLAN bare fiber (non-doped, rare-earth-doped, inventory stock and custom draw), ZBLAN cabled fiber, ZBLAN bulk glass and preform, and AlF3 bare and cabled fiber. These are the mid-infrared gain and delivery media behind the company's own amplifiers, sold as components.
Aluminium fluoride (AlF3) bare fiber, which FiberLabs positions as having a higher laser damage threshold and better water resistance than ZBLAN. It is used for mid-IR beam delivery and spectroscopy.
A cabling service for AlF3 fluoride fiber, aimed at mid-IR beam delivery for medical, dental and spectroscopy work. Protective tubing and bundle options are available.
A custom draw service for ZBLAN fluoride fiber, for requirements the standard non-doped, standard rare-earth-doped and inventory lineups do not cover.
FiberLabs' current stock list of ZBLAN fluoride bare fibers, doped and undoped, updated against actual inventory. It covers geometries outside the standard mass-production lineup.
FiberLabs' standard, regularly produced non-doped ZBLAN fluoride bare fibers, in single-mode and multimode forms. ZBLAN transmits into the mid-infrared where silica does not.
FiberLabs' standard, mass-produced rare-earth-doped ZBLAN fluoride bare fibers. The dopants give emission wavelengths in the visible, near-infrared and mid-infrared that silica hosts cannot reach.
ZBLAN glass blocks and fiber preforms supplied for academic research. This is a made-to-order service with no standard catalogue items.
A cabling service for ZBLAN fluoride fiber. Any bare fiber from the FiberLabs lineup can be cabled, with protective tubing and fiber bundle options.
