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.

The page tabulates roughly 40 part numbers across six groups: single-mode (ZSF), elliptical-core (ZEF), multimode (ZMF), single-clad doped fiber for core pumping (ZSF with Tm, Pr, Er, Ho, Yb, Dy or Ce), double-clad doped fiber for cladding pumping (ZDF with Pr, Er, Tm, Ho, Ho/Pr, Nd or Tb), double-clad non-doped fiber, and coreless fiber for endcapping (ZCLF). Core diameters range from 2.1 to 45 microns on the doped fibers and up to 145 microns on multimode, with cutoff wavelengths from under 600 nm to under 8300 nm. Because this is a live inventory list, FiberLabs states it is updated regularly, so availability and figures should be confirmed at order time.

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.

A custom draw service for ZBLAN fluoride fiber, for requirements the standard non-doped, standard rare-earth-doped and inventory lineups do not cover.
Our application engineers will confirm specifications with the manufacturer and quote for your configuration.
