CO2-laser based fiber coating process for high power fiber application

The generation of high power in active fiber application and the transmission of high laser power via fiber cables both require protection from misdirected laser light. The following paper presents a new approach to removing this unwanted part of light. The deposition of fused silica material on the fiber cladding applied with CO2 laser processes constitutes a robust cladding light stripper suitable for high power levels. The CO2 laser processes are easy to apply, obviate the need for any dangerous liquids and promise greater mechanical stability in handling and assembly.
