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.

ZBLAN Bare Fiber (Non-Doped)
ZBLAN Bare Fiber (Non-Doped)

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.

14 sourced specs
ZBLAN Bare Fiber (Rare-Earth Doped)
ZBLAN Bare Fiber (Rare-Earth Doped)

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.

13 sourced specs
ZBLAN Bare Fiber (Inventory)
ZBLAN Bare Fiber (Inventory)

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.

15 sourced specs
ZBLAN Bare Fiber (Customized)
ZBLAN Bare Fiber (Customized)

A custom draw service for ZBLAN fluoride fiber, for requirements the standard non-doped, standard rare-earth-doped and inventory lineups do not cover.

2 sourced specs
ZBLAN Cabled Fiber
ZBLAN Cabled Fiber

A cabling service for ZBLAN fluoride fiber. Any bare fiber from the FiberLabs lineup can be cabled, with protective tubing and fiber bundle options.

2 sourced specs
ZBLAN Bulk Glass Block and Preform
ZBLAN Bulk Glass Block and Preform

ZBLAN glass blocks and fiber preforms supplied for academic research. This is a made-to-order service with no standard catalogue items.

2 sourced specs
AlF3 Bare Fiber
AlF3 Bare Fiber

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.

13 sourced specs
AlF3 Cabled Fiber
AlF3 Cabled Fiber

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.
