This technology employs a laser-induced breakdown spectroscopic (LIBS) technique to measure, in-situ and in real-time, the constituents of the melt in a process furnace. By allowing in-situ, real-time measurement of melt constituents, this technology will improve product quality by reducing defects. It will increase furnace life by diagnosing the state of the furnace, and provide necessary data to develop and validate computer modeling and simulation.

These processes are currently too costly.  However, due to their high potential there are projects concentrating on lowering costs and making the technology more widely available (such as US Deparment of Energy's Industrial Technologies program).
