Detailed Data Sheets of Fiber Preforms

Fluorine-doped Quartz Tube

The waveguide structure of Triple-cladding Active Optical Fibers (AOF), compared to Double-cladding Optical Fibers, can enable most of the pump light to reflect at the cladding, significantly improving the thermal management of the fiber, significantly reducing the reflection of high-power density pump light at the fragile organic coating layer, thereby greatly improving the stability and reliability of the entire laser optical path.

Fluorine-doped quartz tubes have the advantages of high fluorine concentration, low OH content, and good geometric uniformity. They can be made into multi-layer composite tubes with polygonal structures, and are widely used in triple-cladding Active Optical Fibers (AOF) and related Passive Optical Fibers (POF). Design fluorine doped quartz tubes with matching 2.5mm and 3.5mm core diameters for YDF 34/460/530 active doped optical fibers.
