"Steelworkers will be able to monitor in real time the temperature and chemical composition in molten metal furnaces, saving each steel plant up to 4.5 million a year, thanks to a new laser technology developed by a Swansea University spin-out company."


A bit more info here. An essential component is a gas-swept tuyere through which the laser beam is projected, avoiding metallic accretions which made previous laser-based systems unreliable:
