Abstract

11 kW of COIL power are successfully transmitted through a 20 meter long modified commercial fiber system with optical losses below 10%. The transmission ratio is derived from simultaneous measurement of the laser output power behind the total reflector and the transmitted laser power behind the complete optical fiber system. The fiber delivery system is used to demonstrate cutting of various materials pertinent to dismantling & decommissioning of nuclear installations. Nitrogen and oxygen gas assisted cuts are performed for metal and nonmetal samples, which are made of steel, aluminum, concrete and graphite. The cutting results are validated with theoretical models from literature. The COIL cutting performance is compared to referenced data of laser materials processing.
