Laser cutting/processing in nuclear decommissioning is an increasingly useful technique, allowing access to tight spaces, controlled cutting width, among others. Fine particles are produced as cutting waste, presenting a possible hazard to health, but may also be analysed to investigate the cutting material contents. Here, progress on a diode laser system for absorption spectroscopy for fine particle analysis is described.
