Fluoride single mode ZBLAN fiber patch cord 0.3-4.50um (core diameter 8.5um FC/APC 1.5m long)

ZFG fiber is a composite glass fiber composed of heavy metal fluoride. Compared with the widely used quartz fiber, ZFG fiber has the characteristics of wide transmission wavelength range of 0.3μm~4.5μm and high emission efficiency of doped rare earth ions. In the application field of fiber lasers and amplifiers, in order to optimize their efficiency, through a unique fiber manufacturing technology, we have launched a low-cost production of high-quality (especially low-loss) fluoride fiber single-mode fiber with a specific D-type core. Customized fiber lasers and amplifiers can be designed and manufactured. Mid-IR supercontinuumLVF nonlinear single-mode fiber can achieve very flat and broadband output spectrum due to its excellent performance. (Mid-infrared supercontinuum laser) Mid-infrared spectroscopy and optical measurement. We provide a full range of ZFG fiber products to meet the needs of demanding fiber lasers, and can customize the cut-off wavelength, core diameter, cladding diameter, etc. We provide you with a full range of infrared external line solutions.

Dimensional Drawing

Since the discovery of ZBLAN glass in 1974, a variety of fluoride optical fibers have been developed, including ZrF 4, InF 3, and AlF 3 based fibers, designed for mid-IR applications.

Typical compositions of ZFG and IFG glasses are:

ZFG (Zirconium ZrF4 Fluoride Glass) = fluorozirconate fibers

53 ZrF4 -20 BaF2 -4 LaF3 -3 AlF3 -20 NaF

IFG (InF3 Fluoride Glass) = fluoroindate fibers

40 InF3 -20 ZnF2 -20 SrF2 -20 BaF2

They have the specificity of high transparency from UV to mid-IR: 0.22 to 7 µm and 0.255 to 8 µm for ZFG and IFG (3 mm thick sample), respectively.

Thus, they completely cover the 3-5 µm atmospheric transparency window and partially cover the molecular fingerprinting region, paving the way for numerous passive and active applications.
