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.
Technical overview
Seven double-clad fibers are catalogued, doped with Er, Tm, Ho/Tm, Ho/Pr or Er/Dy at concentrations from 2,000 to 60,000 mol ppm. Core diameters run from 7.5 to 30 microns with core NA from 0.11 to 0.17 (each measured at its own reference wavelength) and cutoff wavelengths from under 1700 nm to under 5350 nm. All have a circular first cladding of 120 to 300 microns and a second cladding NA of 0.50 +/- 0.02 at 1000 nm, with cladding absorption from 0.3 to 5 dB/m at the stated pump wavelength. No PDF datasheet is published on the page.
Features
- Mid-IR Transmission up to 4 micron
- Exotic Emission Wavelengths in VIS, NIR, and MIR
